Am I getting ripped off?

[blissbsm]

Im just curious if i am paying too much or if its in line with what everyone else is paying? I have a 67 firebird convertible that a high school friend of mine is working on for me. I have supplied all of the parts, he is just charging me labor. I gave him a deposit of 5k when the car was dropped off. We are replacing every body panel on this car! When i dropped the car off to him I was told the 5k should get me to the front clip, meaning floors,rockers,mini tubs,quarters and rear tail panel and trunk lid.
So far the rockers,mini tubs and quarters are installed and the rear tail panel is clamped on.
I was informed a few weeks ago that he is out of money and i need to come up with more cash for him to resume. I was also told that it would take another 20k -30k to finish.
Is this in line with what everyone else is charging? Mind you this shop is in upstate ny and this is by far his biggest build ever!
