help a veteran to help a veteran

the 2002 dodge pickup that I use to help transport aid to veterans I distress, has blown an engine. (Due to lack of maintenance from previous owner). It will cost me $3700.00 to replace it with a rebuilt engine. I am a disabled vet on a fixed Income and I have children that need to have a Christmas as well as bills needing to be paid, so what little money that I have saved is going to them. Please help me get my truck operational so that I can continue to help our veterans that have fought for our freedoms.
