Dunes of Babel mod for Half-Life 2

The game idea is in it’s infancy and is still being heavily planed. So far it is going to start out simple with a basic team death match. Later I will add more. I hope to have the main focus to be fun.
I have to opposite problem most other mods starting out do, I am a coder in need of artist and mappers. I am looking for talented people to have creative freedom and submit good ideas. If you would like to help post on the forums or email me Apodysophilia@gmail.com

Basic idea
It is a Desert world. Pillars of light from the sky are the only source of water. Water only is only found here and in great abundance. Constant war for the pillars of light between the outlanders and the assembly. Mix of Low end tech and high end tech found. The high tech is left from an old civilization that left/killed it self out. Things range from Home made guns/knives to very basic laser rifles and vehicles. Maybe basic body augmentations (e.g. arms, eyes, legs, lungs).

Level Design
Caves, with out water and with lots of water
Maybe lush jungle
Arabian Cities with high tech junk
Lush Building, with lots of vegetation feed by technology
Open dunes
Maybe add heavy water irrigation. With both old and new ways.
Ruins of an old tech city

Character look
Beaten up old rags or Neat with beating up tech
Gas mask like thing or some short of mouth covering thing
Maybe Oxygen/Water tank
Guns could be tan or rapped up in rags
Guns could also be colored desert camo
Goggles or other eyewear
Maybe white eyes for some

I am in desperate need of:
Character designers
Modelers
Skinners
Sound Engineers
Mappers
Writers
