I can't help with a shop, but I have a friend that makes windows for old Porsches from
lexan.
He lays the plastic on the glass that he wants to copy and puts it in the
oven for 30 minutes at 350 degrees, just like a cake.
He built a big
oven out of
plywood,
fiberglass insulation, a thermostat out of an old
stove and some BBQ
parts.
Apparently the substrate must be clean and smooth or marks will transfer.
This may not apply to you but some might find it interesting. If you can make the curve, any powdercoating shop will have the oven you need, probably for free or maybe $20.00.
