Mike,
You order their template kit to create your own template. You then send this back to them for a quote. I think it ran just over $300... The kit runs $15 but is deducted from the total cost if you buy...

The kit includes the following:
1, 2 or 3 sheets of clear Mylar plastic
40" x 80"
1 indelible marker
data form
1 template instructions
1 set of EVA foam color samples.
Once you have the kit follow the simple templating instructions. The cost of the kit is refundable upon purchase of a completed pad. Though the templating process is pretty simple, there are DIY video instructions to help you.
