I want a new belly button! Would I need a mini-tummy tuck? (photo)

I want a new belly button. It has been stretched from 2 pregnancies and I am now very fit and want to show my body for fitness model comps. I've been told my skin is to tight above my belly button and I would only need a mini tummy tuck. I'v already had some skin removed on top due to a old belly button piercing. But now I want it all fixed! Please Help!
