Good credit card for paying for IVF?

My wife and I are about to go through invitro fertilization and we think we'll need about $20,000. We have maybe half of that now and would like to get a credit card to pay the difference. We're looking for a card that has 0% for a year, preferably some rewards back (miles, cash, whatever), and obviously a somewhat high limit. Our credit is very good so we should qualify for the good deals and rates. Any recommendations for good credit cards that would fit our needs?
