Seeking 2D art...

My name is Gregg and I am developing a small title as a learning tool so I can build my really cool idea. However, I am strong on Programming talent and weak on art talent. I would like to create some basic graphics as place holders that don't look so horrible it detracts from the game while testing.

If anyone knows of a good place to get top down art (2D content pack, sprite packs, etc.) please let me know. Also if anyone is a 2D artist, I have a small budget for this project if you are interested post some contact information here and I will get a hold of you.

Cheers,

Gregg
