How much do u guys think it would cost me??? In vitro...?

Ok, so..hmm. i've seen the prices for in vitro procedures, but what if the situation is a little different. Let's say a lesbian couple wants to have a child, but they dont want to go thru the problem of having preference of one kid over the other if they use sperm donors...so they want to use one of the girl's eggs fertilize it and put it into the other girl, i've heard that this way both of the parents have legal guardianship of the baby and in my opinion it's seemed as the baby is actually from both parents...my question is? is this procedure the same price as in vitro??
