I understand the decision making process that you have undergone to get to this point and repect your decision. However, I would suggest reconsidering a one-stage immediate reconstruction. Rarely does this produce a result that rivals a two or three stage reconstruction. In addition dermal grafts, such as Alloderm, need to incorporate into the the skin flaps. If this doesn't occur, which is a known complication, the graft and implant will have to be remove and reconstruction will have to start over.
Immediate reconstruction can be performed using the abdominal tissue, called a deep inferior epigastric [artery] perforator flap (DIEP). This is a more complicated reconstruction but gives the benefit of using your own tissue, which feels better and will also give you a tummy tuck at the same time. You might what to find a surgeon in your area who specializes in this procedure.
