Pro Bono Surgery

I have lost about 120 pounds, through diet and exercise. But now the excess skin has become extremely uncomfortable. It causes me pain and discomfort. Which causes me to reduce the amount of exercise I can do now. It has made me physically uncomfortable. Carrying the skin around has become a chore and effects my daily movements. Is there any way to get surgery to remove the excess skin done for free?  I am willing to do before and after photos to show the work done and the improvements that were made.
