Plastic surgery schools in Houston or near that offer discounts surgery cost for Tummy Tuck?

I am very petite 5 foot and 137 lbs but after having 3 children and air scupt lipo I can't get rid of that diastacis recti as well the wrinkly stomach with the excess skin. I can't afford to pay full price out of pocket for a tummy right now and since I am a new homeowner, my debt to income ratio-creditors won't give me more credit. I also don't want any more credit (want to pay debt off not accumulate more). I have heard that there are schools that will do procedures for a lower cost.
