Blood banks are done several ways, depending on where you live, in the US they're regional, they're either independent not for profits, run by local hospitals, or ran by the red cross, you can go to your local bloodbank and request an autologous ( your own) or directed ( family member or friend who matches your type) donation. In my bloodbank there was a time period to store it, blood is only good for 42 days, and isn't the best option after frozen. My bloodbank required a doctor to sign off on the blood request and generally it was done within a month of a planned procedure where it might be needed. Testing will be done on directeds and they still have to pass a standard physical exam and screening questionairre. Edit: just type your area code and bloodbank into a search engine, should give you what you need to contact them.
