Are there really surgeons willing to perform a complete tummy tuck probono? can i really donate my skin?

I don't think so: plus his fee is only a fraction of the costs involved. Good luck

Unlikely: Few surgeons will perform pro bono work unless he or she is doing it for charity.

You can find: anything you look hard enough for. The question is would you want to? There isn't a critical-enough shortage of skin for that to happen and the freebie wouldn't be given for the donation anyway. Most skin is harvested post-mortem. If price is an issue your best bet is to be referred through ASPS or ASAPS
