While I agree, don't see everyone... It isn't safe, it isn't always profitable and some guys aren't worth the drama or the demands they make. That being said... Don't make guys jump through too many hoops either. Don't start out at $800/ hr if you are an unknown, why would anyone pay through the nose for someone with no history and no reviews? Look around your area, see what the going rate is for girls that offer similar services to you who have similar looks. Read their reviews and think about how and why they charge what they do and follow suit.
If you start getting great reviews, then slowly increase your rates, start touring maybe, develop a following. If you are THAT hot, that good, etc. then maybe you are worth $800/hr. (Out of my price range, but some guys, yeah). Think about how much you want to make per week, per month, then think about how much volume you want. volume will probably go up with lower rates, but then again you might end up making way more in the long run. Think business, treat your customers like kings and you will quickly develop a stable of regulars who will probably see you even at higher price points, though they will grumble at every raise in price.
Just being honest with life as I see it. There are tons of hot providers out there with 9s and 10s whom I will never see because no piece of ass is worth paying more than my mortgage payment for a month for one measly hour. Yet there are also hot providers out there (also with 9's and 10's) whom I will, and have seen, that are within my price range, or slightly above, so that an extra coupla days of saving gets me in to see her anyway.
As a newbie, don't price yourself out of the market. Leave that for your elite courtesan phase in a year or two.
