So I finally figured what I can do to help. I'm not sure if you have a keycap solution in mind, but I have dealt with Signature Plastics in the past.
If needed let me know the specifications.
I was just going to contact SP.
Help would be great, thank you.
Specifications:
Standard alpha part ANSI 61 keys, ISO 62 keys.
I guess it would be cheapest to take what they have but I'd prefer if it was Cherry compatible (stabilizers, space bar switch position, etc).
Choice of stabilizers will affect pcb and maybe body construction.
They probably have black and white but what about additional colors: gray, cream, brown (with black lettering)?
With and without symbols?
Maybe ISO languages?
Materials? Edit: Lasered? Double Shot?
Edit2: And a swirl key would be nice!
Edit3: Control keys for CapsLock position and additional blank keys for the spacebar row (even with symbol sets).
To keep it simple, quotes for 5 and 10 units would be fine. Less than 5 will be too expensive, more than 10 won't happen that often. Quotes should include stabilizers.
For the curious, here's what chimera15 found out:
