I hire models. I have 4 sets atm of photos on my hd waiting to become textures/characters & am going on Saturday to photo shoot 2 more models. You need a really good camera too. Olympus is the best IMHO. You can contact models thru your local phonebook, beauty salons also have a lot of clintel that are models. I am forchante because I owned & operated 2 full service beauty shops for 17 yrs. I have kept in contact with all my old clients. You might start off with asking family/friends. I take approx. 500 photos for each model. Sometimes more sometimes less.
