Laser cutter materials

Sent off a few quotes today to plastics suppliers for some acrylic sheets:
Hello, we are running a small laser cutter in our school and are looking for some acrylic/plastic that is safe to cut. We’d like a variety of colours, including transparent. It’s mostly for quick fun projects for kids so the materials does not need to be high quality.
Maximum sheet size is 12” x 20” but smaller is fine like 12” x 12”. Thickness 1/8” and ¼”.
Quantity of at least 10 sheets in 1/8” and ¼”, in maybe 5 different colours each? So a total of 100 sheets including shipping to the address below.
We've had really good success with the demo sheet that came with the Dremel LC40. Biggest issue was venting the smell, but it wasn't too bad for small jobs.
The cheapest sheets I've found so far are from Shop3D.ca for 1/8" at $8.75 per sheet. It's not bad for retail but wholesale cost is half that, but you'd have to cut it down yourself.
We had a big issue with using large 1/8" plywood sheets from Windsor Plywood: it was just too warped and bowed to lie flat on the bed. I tried every trick to flatten it out, including spritzing water and applying pressure but no luck. It would save alot of time just getting pre-cut flat sheets.
Dremel does sell its own pre-cut sheets but at ludicrous cost, around $12 USD a sheet!
