These guys are absolutely right, but I'd recommend you start by reading the Forum Guidelines, if you haven't already. A "must":

To what the guys above have to say, I'd add the following: When doing your homework on providers, look for those who have
consistently good reviews over a span of at least 3 - 6 months (the longer, the better). We recently had one who had a flurry of initial positive reviews, who proved herself to be a total whack job -- spammed the site with her ads, then got abusive (and that's putting it mildly) when called on it. I myself wrote a glowing review of my positive 1st session with a well-known provider, only to subsequently regret it. On the other hand, there are otherwise stellar providers who have an "off" or bad day every now and then -- take this into account.
Good luck!
