Sperm Donor..??

So my wife and I tried insemination On Sept. 10. AF is due tomorrow and so far test are negative. I know I'm not officially out until AF shows but just in case....what are some options as far as finding a new donor? I'm afraid we have lost our known donor due to some friendship arguments. 😑 I know online sperm banks are an option but that's a little pricey for us. We don't really have any other willing male friends. What are some other ways to go about finding a new donor? Any tips would help. Thanks in advance.
