Ttc... free donors?

Hey everybody. I've been ttc for 3 years with no success. My doctor recommended IVF, but I cannot afford it. I've just purchased an ovacue fertility monitor. I'm excited to use it, but have to wait until the start of my next cycle. (I'm on cd6.) I don't have any problems, the problem is the sperm. We tried with donor sperm from the bank and iui, but it was unsuccessful. My doctor reassured me that the rates of that working are low, anyway... We're considering finding a local man to donate for us (using one of those websites for connecting you with men willing) but I'm kinda scared to go that route. Anybody have any advice?
