I agree that you should start by shooting at home. Besides the cost, expect that 50% of your "confirmed" appointments will not show up.

Always get your paperwork done BEFORE you shoot. I sent a guy home a few weeks ago because he wanted to "negoitiate" the terms of the release form. If he doesn't agree to the terms as-is, you've wasted your time and he'll still want to get paid.

If you advertise for models and include a phone number, be prepared for tweekers calling in the middle of the night for 3 months after the ad stops. Use email only and don't call back unless they send a picture.

The best way to get models is walk right up to him and ask if he wants to model. It's tough, but you're more likely to get the type you're looking for.
