two day job bro...two day. I take the wheels off and clean every inch inside and out. I don't use fusion cquartz or any other nano product. My abilities are right up there with professional (minus wetsanding!)
I wasn't hating on you at all though, I wish I could get a gig doing it for a job but for right now its a fun hobby (since i'm unemployed!!) that score side work.
I apologize for my typo; i meant to say "...for a two day job..."
My point is, if you're charging $175 for a two day wheels-off detail, I don't have to prove your abilities are NOT "right up there with a professional" as you're already proving it. As most of us should know, price alone isn't a complete reflection of skill level. Skills, experience, a diverse portfolio, and other factors including price reflects true ability level.
Clients want to see a high universal standard on all work. Not just one or two cars, not just one make or model, and not just over a short period of time. In addition, safety is a major importance for high end clients as they want to make sure mistakes aren't made. Taking thickness readings (to include ultrasonic readings on composite materials, like an all carbon fiber body:

It's not easy, and every job is earned through your past actions. Competition is high, this type of stuff isn't a necessity of life or owning a vehicle, and the economy is rough.
I assure you this isn't a shot at you, or anyone else in particular, but rather meant to inform those who might not fully understand how much goes into this stuff.
P.S. If you doubled the "$720" figure, you'd be closer to the actual price.
