It's hard to make a judgement based on two reviews. One OK, the other "meh". The harsher of the two made it pretty clear that you were not what he was looking for, and should have not gone through, gave you a percentage of the agreed time fee, and not subjected you to a weak review.
If your website prices are correct, then for time charged and services rendered, they are slightly higher than the market, IMHO. The thing that surprises me is seeing the reviews from folks that go to a body rub woman, pay 200-300 for a HJ or CBJ, that's all they get and they are happy with it.
AZ rates are based on the cost of living compared to the rest of the country. Other places are less, reviewing some of the other regional ad boards. Other places are more. It's just an economic fact of life. I could make more money living in CA or NY doing the exact same job, but the cost of living eats it up.
As far as trying to bargain down pricing, it happens. A friend shares some of her stories, and it blows my mind, but it's a result of idiots calling out of her BP post, and those are the "spur of the moment" types, not the serious guys that research, read reviews, read websites before deciding on calling (like me).
To be honest, two reviews does not make a "higher end provider". As suggested earlier, please increase the number of photos on your website. Give me a better picture of the woman I'm thinking of giving my hard earned money. Diversify your advertising base. BP does not attract the quality customer you are looking for. There are other review sites with advertising that you can post on daily. Get your ad up here. Participate in the conversations, instead of saying "I'm wonderful, and you indigent, cheap ass jerks in Phoenix suck."
Personally, I have a major thing for adult, grown up redheads. I enjoy sharing seriously passionate multi-hour encounters with them. Give me a relatively tall one, with hips I can grab a hold of and share something fantastic, and I'm all in.
Then again, I'm not "seeking wisdom and bargaining you down". I'm seeking a companion for a couple of hours of total, unmitigated sexual excitement, passion and fun for both of us that leaves us sweaty, spent, exhilarated, tingling, smiling, and multi-orgasmically blown away over the energy we share together.
Based on the limited information you provide about yourself, I just don't see myself risking the investment or time hoping for something that doesn't seem to be there. Please feel free to PM me if there is something that I'm missing or if you'd like any clarifications. Like I said earlier, I have a thing for adult redheads.
Check yourself as well before tossing rocks.
