Most people here wont work for credit since well, credit only work if you have a new blockbuster game. If everything that has been produced for whatever it is, is promising then ill gladly help, but you asking alot for nothing. Modeling something is only a 1/3rd of the process, the person would then need to uv map and then produce the texture, anyone can bring the model into fpsc, so you really handing off most of the work...
Sorry to be a buzzzkill,
Try learning yourself, the great graphics resource has a list of tutorials that is perfectly suited to what you need.
If you have made alot of progress and shown that you are determied then ill help.
An thats all i can think of right now,
