I'll be clear, bluntly honest, and may repeat myself to emphasize certain things I am about to mention. Plus I may piss you off!
I'm a freelance photographer for about 4 years now. I've paid models for about 1-2 years to model for me to build a solid collection of photographs to resale in any way I see fit, but right now I primarily use them as poster sales. The modeling types that I have a chance to sell must be of female models that are nearly naked, in tiny bikinis, lingerie, implied nudes or actual nudes. If you want to get paid, and work in the freelance modeling world... one or all of those types of modeling may be the ONLY way you can earn any money from freelance photographers. I know most models want to get paid and be clothed as much as humanly possible, this will not happen unless it is outside of the freelance world where you are working with modeling/talent agencies.
