Try a local sign makers. That's what I did, called round them all until someone said they had some. This was ages ago and you're based on the moon, so I can't recommend a specific one unfortunately.

I just happen to be in that business
You'll find most suppliers get the material in 6x4 or 8x4 sheets. Plus Try to go straight to the distributor or main supplier rather than a signmakers, you'll save a good 50% at times.
From the top off my head a 8x4 sheet of 0.9mm PETG 8x4 cost me around £16 (Poly prop around £2 more) + vat a few months ago. Acrylic isn't too disimiliar I don't think, depending were you go.
