Here's another possible area to help grow your business. I don't know, maybe this is coming out of left-field, but have any private sector Cyburbanites ever had a client from a non-profit organization? If so, is the fee any different for them from your typical set of governmental clients? How did you reach out to them?
Since many of these non-profits are comunity-based organizations, I would assume they prefer to go with local consultants they know and have trusted. Perhaps the non-profit community isn't able to afford the private sector consultant fees. However, when I was a grad student, there was an umbrella organization for over a dozen Detroit-based non-profits called the Gateway Communities Development Collaborative. They pooled their money and hired a high-profile consulting firm in the southeast Detroit area to develop a land use plan for the southwest Detroit area.
I am sure it is rare, but have any of you scored a project with a non-profit?
