I believe I can help you out. I've assisted in production with quite a few sites, from
www.jismjunkies.com, www.joepornstar.com ,
www.voyeurwindow.com and
www.extremeholly.com, just to name a few . I manage 8-10 girls and constantly interviewing new models here in Phoenix. Rates will vary depending on what type of scenes you are looking for, the niche, how exteme you want the models, and basis of storyline.
I have all my own equipment and am able to produce out of my own studio or on location. Hit me up on ICQ and let me know what you have in mind. I'm usually around, though I'll be doing a lot of editing and it may take me a bit to get back to you, but I will for sure.
I have proven and tested female as well as male models, pretty much any kind of niche you'd want to fill is available.
