I have friends who want to escort. How should she get started in escorting?

If they want to give it a shot, I'd have them make fake accounts at TER and ask the Chicago board for the best agencies. After that, they should look up the agencies' websites and check out the employment information. 70/30 is a very good split for this industry; 60-40 is more standard. After that, they'll need to send pictures to the agency owners. If the agency is interested, they'll set up a phone interview, where your friends should ask about the split, screening, who pays for what, how long they've been in business, their clientele, if they've ever had legal issues, whether they do incall or outcall, advertising, etc.. I personally prefer working with female agency owners, but there are some good male ones out there too.
