I agree with Tom, you need to find early adopters and groups. I am launching a new application and I have detect some meeting and events to launch it because my app is about doing networking, so that will be perfect to test. You can read the information of the app here: http://let-s-app.com/ I think networking can be fun even if it is a need. Or if you prefer you can search on Apple Store: "Let's App" and test it.
