That was beautiful, Mr Duck!
Seriously though, if you're looking at green guns, visit SOCOM Tactical. They aren't great for big repairs, but they sell some nice guns with free two-toning (which they do in green, I can send pics if you want). Just don't ask them to completely disassemble your gun or it'll end up like a Lego set put together by a three-year-old.
With pistols...it's a tricky one, cause you have three options here. You could either go for a gas non-blowback one like an HFC (the ones listed on the pistol guide), you could get an AEP (CYMA make a half-decent Glock 18) or a cheap blowback gun like a KJW. Their Glock 23s and Beretta 92s are great, but the others are pretty hit-and-miss...
Hope this helps.
