Lexi, with your looks and physique, I recommend Singapore. English speaking, affluent, safe, clean, warm, great location for weekend trips. Guys over there (mostly asian customers) would be *very* interested in someone like you. Presently local girls charge about C$400 an hour (due to rarity) and other imports (chinese, thai, etc) charge about C$100 an hour. You'd be in a position to charge at least C$300+ an hour. There is the Ipanema or Brix, where SPs hang out for guys.
You'd be in a grey area though since you would be operating independently but a lot of other agencies do it already. Check out sammyboyforum.com.
