Having a degree from a university doesn't make one intelligent by default. Although, there are certain things that one does assume from such individuals. Making well formed arguments and utilizing the English language in such way that they can be understood are some of these things.
I don't really care if the individual that I meet has a degree. What I care about is whether or not they will be morons. Karla, for what I have seen, you are not a moron and I would love to meet you some day. I'm sure most of the guys have a similar attitude towards this.
If you feel the need to increase your rates, then do so. You may loose some of your clientele and perhaps place yourself out of range of others, but you can experiment with it and see how the market will react.
I have experimented with ladies that offer a $$$ service to ladies who offer a $.5 service. To be honest, there is nothing in the $$$ range that the ladies in the $.5 don't offer. There have been some $$$ ladies that offered sub par performance and are as smart as a failing 6th grader. There are ladies that are in the $.5 range that are extremely smart and made me feel great.
It is ultimately up to you as how you want to market yourself. As I stated before on other threads. Make sure that you have an exit strategy. In this business, it is a race against time (and not everyone gets to meet prince charming). Not everyone gets to stay beautiful for the rest of their lives. Make sure that you are learning a trade, earning a degree or saving money for the future. You don't want to be the 70 and trying to make a living at this.
