check the yellow pages: plastics-products -wholesalers/manufacturers.
in the past i've used my local supplier (ResiPlex, Geelong) for many acrylic/perspex pieces. i usually supply a fullsize template made of thick cardboard for them to work off. they then use their computer-operated CNC router and cut it out.
perspex/acrylic
is expensive. a 20~25mm piece around 600x400mm, with hole cut out for sub, is unlikely to cost less than $100~150, cut to size.
if you don't need any holes cut in it, use glass. much tougher and cheaper. silicone it into place.

thanks mate, yeah its just to make a window for my amps, im thinking glass is the go, hell of a lot cheaper, and like u said if u dont need to cut a hole in it...
cheers
