Your prices seem too low. If you're doing the job with premium Adam's products, and putting in the time, charge for it. As a consumer, if I was looking at detailers and saw your prices I would assume I'd get what I paid for. It is a luxury market, not to mean that only rich people get cars detailed, but even average folks who pay for detailing I think realize it is a splurge that they enjoy.
Best wishes for a successful business!
