Do not use strippers or prostitutes .... they are just not worth it .... bad models and to expensive ..... find them on the streets, local beauty contests, internet profiles with pictures. You might also poste an add in your local paper but expect to get response by a lot of ugly girls ....
Salary ... Well it depends where in the world you are located.... In USA and western europe about $40-80 pr. hour ... for amateur models
In estern europe same amount for a day ....
