Try
www.divas.com.mx for very attractive, independent escorts if you don't mind paying U.S. prices. Be sure and click on the "Guadalajara" tab. There's a forum there where you can read comments about the women. You may or may not have problems with a woman coming by your room. I've walked into hotels with a date looking like I own the place and have never had a problem. But many of the nicer hotels do have no-hooker policies.
Look at
www.internationalsexguide.info for English language postings.
I would recommend Rape, a massage parlor, which provides a clean environment, reasonable prices (about $100 for an hour), and consistently attractive women (no 9's or 10's though). See
