Need some help in getting my car fixed

Started having problems with my car running rough.  So into the garage we go.  Turns out to be a major disaster - a blown head gasket.  Total comes to 3646 dollars.  I have a Gateway Tire and Service credit card and have managed to raise my limit to 2700 dollars so need to raise 1000 to cover the balance.  I really hate to use this venue but have not been able to raise the thousand required.
Any help will be appreciated.
