Joining referral networks like BNI or local chamber groups can be a great way to help you network and generate referrals. The most powerful way to use this strategy, however, is to grow your own.

1. Create a blog network
2. Interview each member for a teleseminar series
3. Create co-branded white papers
4. Do endorsed mailings
5. Put on a group workshop
6. Distribute marketing materials and offers
7. Bundle each others products and services

With some careful consideration and a little effort you could build a referral network that would rival any sales force.
