I need tuned imports and other cars, mods and so on related to underground street racing. The game is Cruzin.la and the booster packs will contain items with codes that will be used to add items to inventory in the game. There will rare collectible art as well as limited production runs of various items along with the common cards, etc.
I also have BattleCodes.com which will need mech type art. Tanks, armor, etc.
Did you find anyone? I just completed development of a game and the independent artist that I used was very good. Let me know if you want his details. He's in the UK, but I largely worked with him online and it worked out very well.
The guy who did the work for me is called Paul Loudon, his web site is paulloudon.com. I just had a look at his portfolio on his site, and he's not yet put up any of the trading card stuff that he did for me, but some of those characters are here.
