If you are going to participate in this world you owe it to yourself to obtain VIP.

It would allow you to compare the reviews for the two ladies in you are inquiring about.
You could also do a search on the discussion board and learn about the agencies they work with.

As it is this is the best help I can give you.

Good luck.
