How about you interview prostitutes where it's legal?
3 places it is.. Canada, New Hampshire (I believe check the prostitution wiki) and Nevada
Another thing you can do is to make your life easier (less stress) is find prostitute forums or websites and ask them there.. virtually then there is no physical meet..
Why do you think what prostitutes do is bad? You already have a judgment about it since you want to help them change.. anything there doing is not bad.. it is merely just a society judgment of bad.. I would suggest you stop adopting society labels and judgments..
Here is also another idea.. you could advertise on craigslist and pay them for their stories via the internet w/ PayPal.. see my imagination loves to help?
