If I understand what you're seeking, you want to make (or have someone
make for you) about 20 clear plastic 2 x 2 x 1/2 arrow shaped molds.

A gentleman named George Gassaway wrote an article from SNOAR News

+"vacuum forming" +"small jobs"

Mcneal Enterprises (this is an article which links to McNeal)
Moorland Plastics (UK)
Usually you'll have to contact them with specifics so that they can
give you a quote.

then select your geographic area. You should be able to get listings
of potential businesses.
Please ask for clarification if you need it. Knowing the upper limit
of what you want to spend would be useful, as well as your geographic
area (in general).
