Also, keep this in mind - a lot of the newbie-friendly ladies have fantastic oral skills, so even if you don't want the full meal deal with some of them, you can just go in and get your knob polished, and that counts as a reference.
Once you have two references under your belt, would strongly recommend you to get a P411 account, as this will greatly speed up the screening process for the ladies who accept P411 references (many of them do). You can get a P411 account without having any references, but you'll be forced to give up some personal info when doing so.
And remember an important rule when contacting ladies... BE NICE!! I'm not saying that you're not, but many guys 'round these parts feel that just because they're paying the ladies, that gives them carte blanche to be an asshole. Remember, this is a business transaction when you get down to it, so be courteous and polite, as providers can (and often do) communicate through back channels, so if you do something to get on one lady's shitlist, you can end up on many more.
