William:

Congrats on getting this job. Your client must know you can do it. As
to the pricing: I don't have a good idea for you. Here's a quick
idea: they might have a budget for this (won't hurt to ask). Also,
snope around other refinishers in your area. You might ask them what
they charge for a smiliar item. This "competitive analysis" is done
all the time and is perfectly legit. You can also do, what's your time
worth x a rough guess of time. Also, if you're starting out, you might
want to "low ball" this job to get and secure the business and the
client reference. Tho, watch out for this, your client might have more
work and they might get use to your "lowered prices".

Good luck!
