What ^he^ said. In addition to my own project it would be nice to help someone, but I need to know what kind of help you want. I can help with these things:
Map design
Triggers (including JASS)
Custom units/buildings
Possibly custom abilities/spells/upgrades (haven't as much experience yet, but I can try)
Just don't look at me for art. That includes models, textures, music, sounds, and such.
