Reddit mentions of The Internet Escort's Handbook Book 1: The Foundation

I've done some research on working conditions of sex workers. My recommendations:

• Be prepared for the work you do. Read for example this book.
  
• Be particularly prepared for what many sex workers say they suffer most: the stigmatisation.
  
• To answer your question: Except for the 4th point in your list: Switzerland might be the place to go although competition is getting tougher and tougher.

I'm a client, not a provider, but these are resources that I've seen other escorts recommend to those just starting out:

1. Although it's a little dated now, check out Amanda Brooks' Internet Escorts Handbook series:
   
   https://www.amazon.com/Internet-Escorts-Handbook-Book-Foundation/dp/0978094409
   
   
2. Check out Safe Office. They have sex worker only forums + blacklist for verified providers: https://safeoffice.com/lp/
   
   
3. Read /u/jo_violet's post history. She runs an agency, and has a lot of great information for those just starting out, including new agency owners.

amanda brooks has a good rep.
