I'm from the DC area and I can see how an image consulting service would be beneficial. However, I would never, ever, pay for something like this from someone who is an unknown quantity. You need to have a successful track record that shows you know your shit, and I don't mean lame testimonials (most of them are lies anyway). Check out this dudes site and see the way he does it. He has posted dozens of videos on tips and techniques covering everything from clothing style, haircuts, diet, working out, etc. If I were in the market for a consulting service like this, I would buy from him because he has put a lot of content out there to give me a good feel for what he knows and can do.
