IMO you're focused on trying to convince the wrong people. You should be figuring out how to sign up clients, sell them the product make a lot of revenue, then you don't need angel investment. In the case you have growing revenue have hundreds of clients, and you just want to blow up at that point there should be no reason for any angel to turn you down. If you have something thats making a lot of money and have a huge market, then angels will take the effort to learn about your market and what you are doing.
