Anytime a woman looks that good, with no web site and no reviews, it has been my experience she changes her number and name to escape any connection to the subpar service she provides. I would pass.

the url "mi-sophia60-bianca" looks too similar to "mi-stephanie106-stephanie1" that was reported last week as a rip off.  I'd say unless you have evidence to the contrary, that's enough to fly the red flag.
