I have been trying to set up a meeting with a provider but they want a name of a previous provider that I ahve been with. That is the problem...I haven't been with one, yet. How do I go about getting around this problem. thanks for the help

The high end and active posting ladies are very careful about recommendations. The only way around this is to see a more high volume lady and then post a review about her. Even if this lady will not return the other providers call, she can at least read your review and check you out that way.

In addition to what MichaelCA said, you could also check into joining a service such as RS2K (www.roomservice2000.com). I don't know if it would be worth it to you, since i checked there Iowa section and it's practically non-existent, but it may help.
  Some lady's in certain areas will take a RS2K verification in place of a provider ref.
