Cheers guys. The pics are still not where I want them to be but that's down to the lighting and camera.
I designed it for 6mm sheet, which in hindsight was a little bit too thick. It's sturdy but heavy. I think 4 or 5mm would be optimal but the drawing needs to be adjusted if using different thicknesses. Colour is opal white.
I got it cut at absoluteplastics.com.au, not cheap at around $400 but better than some places quoting $950
I think using thinner sheet would make it cheaper (and lighter).
