This wouldnt be a problem except that I live in Baton Rouge, LA where even a slightly compromised radiator can be a problem in the summer. Unfortunately business is very slow and I cannot presently afford to replace …

Get a new radiator. It’s overdue yesterday. I recommend calling friends and family until you find someone who will give you money. If you do use some stop leak stuff, follow the directions to the letter or it might not work at all.
