Looking for a material vendor: Green see through plastic

[Nubgan]

Hey guys,

I am making some scenery for an armies on parade board and I am looking for a transparent material that is lime green/bright green, either a plasticard or perspex type material that I can easily bond. I am making a Necron Obelisk akin to the ones found in the original dawn of war games, it will be housing a bulb/light of some sort to make it 'glow'.

If you can think of anything that fits the bill please feel free to post a link below. UK sellers please, any hardware store or hobby shop you know that sells it, please consider I live in Leicester, or suggest them if they have a mail order service.

Thanks all!
