If you're the founder, you need to pitch to investors, never, ever hire someone else to do that. We were in the same boat a while back, and didn't have a network that we could directly raise from, nor could that network connect us to someone we can raise from. We foolishly hired a law firm to represent us. They claimed they could bring in investment from their expansive Rolodex of Angels and VCs. The emails they sent were awful and made it look as though we couldn't do the job ourselves. "Our client is raising money..." is how each email started. As an Angel Investor myself, I know how ineffective and detrimental those emails can be. We pulled back from fundraising and started to expand our network by talking to more people (not asking them for anything) and offering our help in any way we could. It's difficult if you don't have the network - difficult, not impossible. I urge you to sit down with co-founders and staff and learn more about the opportunities within your combined networks, and expand from there. Meeting people from behind a computer is especially difficult, so go to events and mingle, but don't schmooze.
best of luck.
