Your best bet may be to go the “Web 2.0” Venture Capital route. Make an implementation, get together a killer 2-minute demo and 3 minute pitch, visit Sand Hill Road to beg for get capital for building the patent portfolio. Demonstrate how you are building a business that will generate cashflow and you should get some seed capital. At the very least, you should angle for some Angel money for more implementations. You have past form that demonstrates that you are not a flake, you just need capital.
I can ask around for entry points and names to beg. You will be cutting in an external party for at least the first 3 years of your company, and they may demand that you ork in certain ways, but it’s either these guys or a Bank/Credit Card Company. Remember to ask for more than you need!
