EDIT: I thought OU meant Oklahoma so ignore the part about planning a trip to the bay area
I've only raised investment dollars here in SF, so others may have better tips on doing so from other places, but perhaps I can add some insights as well as I didn't have much of a network to start either. To begin with, I'd go to work on your AngelList page - both yours as CEO and the company's. It's a great chance to clearly lay out your company and your message. It also forces you to both think about and articulate a number of items you might not yet have done, but will need to have to be effective in meetings. From there, once that's set, you may get investors asking you for more information but I'd also of course suggest finding investors whose stated interests (and perhaps checkbook) demonstrate that you could be of interest to them. Getting warm intros is MUCH more effective but if you don't have a network, it's possible to start this way and then push your investors to introduce you to more people. That said, in doing this and other work, I'd still suggest planing a trip to SF/SV for a week to meet with more investors. Many of my earliest investors came from all around the country and I've only spoken to them by phone, but there are just so many here in the bay area. Anyway, I'll let others chime in with other advice, but I'd start by getting your AngelList page optimized. Good luck!
