The map is actually 99% based off a Quake map, I can get screen shots of the entire map from birds eyes, I have attempted a recreation in UnrealED, I can show you that as well so you can see the design on grid, I can even show you the basic structure in an OBJ file exported from UnrealED, which you may even be able to work off in 3DS Max.
The original map is abit big compared to Halo, because you can move so fast, I'd like pretty much a small version with an ancient structure theme (Think Warlock/Sanctuary). The map will be aimed at competitive play and will focus mainly on Team Slayer, but also KOTH, Oddball and CTF.
If you're interested, please reply in this thread and give me some examples of your previous work. This is my 1st Halo project, but I have high standards
Here are some screen shots to give you an idea of what I'm looking at:
