If you dont mind asian then i would recommend Joanne from craigslist.
Personality and attitude should be more important for the first SP you choose because it's an experience you want to remember in a good way. Joanne is a nice girl with a good attitude. If you are nervous she will be able to put you at ease.

Her service should be plenty good enough to satisfy a noobie, unlike some of the more veteran chinese girls that may be too extreme for a first experience.
Be warned, once you get into this hobby there's no turning back!!
