I went through a similar experience recently. My solution:

1) Find a place where startup people hang out (in San Antonio, there's a co-working space designed for this called Geekdom). Startup people are rarely found in big companies.

2) Find ways to get involved in the startup community by volunteering or just helping others. You'll determine very quickly who are the quality people and who you'll like working with.

3) Get an idea and go talk to everyone about it. Ask for their advice and get mentored. Even if it's a bad idea, you'll develop relationships and they'll connect you to other startup people who can help or possibly get involved.
