Yes. If by “custom-fit blackout window inserts” you mean a removable panel that fits inside the existing window opening and seals out streetlight, there are a few good options.
Indow Windows makes Sleep Panels specifically for this problem. They are custom-made to your window dimensions and use a compression-tube edge that presses into the existing frame, rather than requiring screws or drilling. Indow says the Sleep Panels block 100% of incoming light and can also reduce outside noise by up to 50%.
That compression fit is particularly attractive for streetlight pollution, because ordinary blackout shades can still leave a bright halo around the sides and top.
Around Frederick, MD, I'd ask a custom window-treatment company specifically for a removable, frame-sealed blackout insert, rather than simply asking for “blackout shades.” For example:
These businesses specialize in custom-measured window treatments, although their normal offerings are shades/blinds rather than Indow-style rigid inserts.
For your particular goal—getting the bedroom genuinely dark at night—I'd start with Indow. The important specification to emphasize is zero light leakage around the perimeter, not merely “blackout fabric.”
If you tell me your window type (double-hung, casement, sliding, etc.) and approximate width × height, I can look for the most suitable options and current pricing.
If you need a rigid, custom-fit insert that wedges directly into your window frame to completely eliminate light pollution (and often help with street noise), a few specialized manufacturers and alternative custom solutions fit the bill: 1. - [Indow Windows](https://indowwindows.com/products/blackout-sleep-panels) :…

Would you prefer an acrylic frame insert (like Indow) that preserves your window view during the day, or a permanent blackout shade/covering ? Let me know and I can help narrow down the sizing or installation details.

Yes. If you mean a rigid, removable panel that is custom-fit inside the existing window frame and seals out the glow around the edges, the standout manufacturer is Indow.
For a conventional custom blackout shade/blind rather than a removable insert, these are nearby options:
For your particular problem—streetlight/light pollution—I'd investigate Indow first. A conventional blackout shade can still leave a bright halo around its perimeter; the appeal of the Indow design is that the panel itself seals against the window frame.
If you tell me what type of windows you have (double-hung, casement, sliding, etc.) and roughly how many, I can compare the best options and estimated cost.

If traditional curtains or blinds are letting in irritating slivers of light around the edges, custom-fit window inserts are a great way to achieve total darkness.
The premier and most well-known maker of true, custom-fit press-in window inserts for total darkness is:

Yes. If you specifically mean a removable, custom-fit insert that sits inside the window opening and seals out streetlight, rather than ordinary blackout curtains, there are a few good options.
Indow Windows is probably the closest match to what you're describing. Their Sleep Panels/Blackout Panels are custom-made to your individual window dimensions and use a compression seal around the perimeter. They press into the existing window frame, require no drilling, and can be removed when you want daylight. Indow says the blackout panels block 100% of incoming light.
They are particularly interesting for your situation because the seal around the edges addresses the annoying glow that conventional blackout shades often leave around the perimeter. Their listed price for blackout panels is currently about $27/sq. ft. for orders of 10+ inserts.
Since you're in the Tampa area, you could also ask a local custom window-treatment company whether they can fabricate a removable interior blackout insert, rather than simply selling you a blackout roller shade.
A few Tampa-area companies worth calling are:
My first choice would be Indow, though. If your goal is "I want the bedroom genuinely dark, including eliminating the halo of light around the edges of my blinds," a compression-fit insert is a much more direct solution than another conventional shade.
If you give me your window type (double-hung, casement, sliding, etc.) and approximate width × height, I can also look for the 3–5 best custom blackout insert products available for your particular windows and compare their prices.
If you are dealing with disruptive light pollution (like streetlights or car headlights) and want a true custom-fit **insert** that goes inside your window frame rather than traditional hanging drapes, a few specialized manufacturers stand out:

Other alternative brands approach total light control with custom-made solutions, though they usually take the form of precision shades rather than press-in acrylic/MDF panel inserts:

Yes. If you mean a rigid, removable insert that fits inside the existing window frame and seals out essentially all light, rather than ordinary blackout curtains, there are a few good options.
Indow Window Inserts makes custom-fit Sleep Panels specifically for this problem. They're measured to your window, press into the existing frame with a compression seal, require no drilling, and are removable. Indow says the Sleep Panels block 100% of incoming light and can reduce outside noise by up to 50%.
That's the option I'd investigate first if streetlights are keeping you awake. The compression fit is particularly useful because it addresses the thin halo of light that often gets around the edges of blinds.
I also found several local companies that could potentially fabricate or install a custom solution, although I would specifically ask whether they can make a removable, frame-fitting blackout insert, rather than simply selling blackout shades:
My recommendation: If your priority is maximum darkness for sleep, start with Indow Sleep Panels. If you tell me roughly how many windows you have and their dimensions, I can also estimate what an Indow setup might cost and look for a Jacksonville-area installer/fabricator who can make something similar for less.
