I'm thinking bout making my first outcall what's the chances of Le showing up or the provider not being who they say they are

Check out the reviewers. If there are a lot of reviews and the reviewers have seen a lot of ladies you shouldn't be worried.

as long as you, pick a well reviewed provider with a good rep.  get vip, read the reviews, thats the key.

The key is to see a well-reviewed lady.  There is no substitute for doing your homework.
