Car has died

My car  has died on me. It is an older car, 1995 Chrysler LHS. The part it needs has been discontinued. Found one online,with shipping will cost $450.00. This is half of my husband's monthly salary (he is a school bus driver) With the kids home, we need help to get this part. For those who would like to check the part is a body control module, part #4759570. We have been laughed at by a few part places because it is a hard to find part. Any help would be greatly appreciated! Once school starts back up we will be in desperate need of this vehicle.
