Welcome to Susan's Place. You probably have complicated matters a little and it will probably take a little more work to fix things. The scrotum is normally used as a source of skin in the surgery. If the incision isn't properly placed, some surgeons will refuse to do surgery. Other surgeons will have to consider another source of donor material.
You should have a replacement source of hormones for health reason if no other reason. Because of what you have done, I suspect most any Endo will want you to have some therapy before they treat you. Yes, we all know how bad dysphoria is but to a medical professional it might suggest a person could be harmful to themselves.
Cost of surgery will vary depending on the surgeon. Some of the out of country surgeons might charge less but in the United State, probably around $25,000.
