I get most of my models at this link. But I am in southern California and theres models every were here . This link has thousands of models all over the USA with a large listing of models who will do nude work of some kind. Its really not that hard to find the models , I have even ask gals in line at the local grocery store to pose for me. Another idea is to contact some of the amature photographers that have nude photographs of models in there listing. You could tell them your needs and pay for a part of there next shoot in exchange for the photo's . If you want paticulars you can IM me and i will help you explain to the photographer what your needs are.
