'High' price does not always equal high quality, true enough.. But.. High quality generally draws a high price.. The more work I have done the better my artist does on the price, I also show up early for my appointment and tip well. I believe all these factor in to pricing, as well as we have lots in common and chit chat throughout my sessions. Its no secret that personality can affect pricing(in any trade like this) some customers can be extremely difficult to deal with.
I would be inclined to believe the initial quote was given to make you aware of what you could be up against financially..
I've also herd some artists work commands nearly 2x that($100/hr).
Do you like you plan and talk to some other quality shops/artists and let us know what they tell you.
