Find a local company that would be able to ingrate it into their system without fee or nominal and use them as your test team. A midsize company that is looking to upgrade existing services would be ideal. Offer then unfettered access to help and allow them the option of customization. Getting them vested in the cultivating of the new product will bring value to your product rather than insisting they take a jump of faith into a non proven system.
This will involve knocking on doors, I don't see you being able to get this kind of access at a networking event.
