Unless you're willing to pay, you're going to find a hard time finding someone on any forum willing to do your bidding. If you would like some quick, low-quality models, visit the 3DGS Acknex Unlimited website. You can make the adjustments you want.

If you want high quality models, there are some listings on the 3DGS main download page. Of course, with every good thing in life, they come at a price!

Otherwise, you're going to have to teach yourself how to model or take some courses to learn the basics.

Best of luck!
