Need a co-signer ASAP

Needing a co-signer for a $3k loan to help cover expenses while out for surgery for diverticulitis and renal cell carcinoma on my kidney. Been at my job less than a year so don’t qualify for FMLA. Ex wife destroyed my credit so can’t get approved by myself. Have a good track record of paying bills on time, just don’t have anyone in my family that doesn’t already have a loan tied to them or can co-sign. Need to get it done this week because my rent is now behind so I need to catch it up and pay all Mays bills in advance because I’m going to be out a minimum of 4-6 weeks and with a wife that is working part time on top of college and 5 kids to provide for I need to have everything covered and get back to work as soon as possible
