most likely no one is going to dish out a model just for you and this game we know nothing about.
I'm sure if you provided proof that this game is well into the stages of development so that the persons hard work might not go to waste (as it does 95% of the time) you might have a better chance of actually getting something.
a lot of people make their own models for their own projects, why not try that?
heres some products for producing your own 3d models, the first two are free.
