I've done the evap swap once, on my own car. I concur with Ron's assessment. It is not actually a difficult job. Just a large number of parts to disassemble and reassemble. There are no impossible to access fasteners, nothing requires 300ft-lbs of torque to break loose, and you don't have to stand on your head while working on a component you cannot feel but not see. Shoot, you barely even get your fingers dirty.

I broke one $3 piece of trim when doing this job on my then 16 year old car. I'd rate it as low risk of damage.

Something in the range of $2000-$2500 seems to be the median cost. Below that I'd be worried about the job being done correctly, above that I'd get another quote.
