I have no experience in this so take my opinion with a grain of salt but what about charging for support contracts? While the project is open source and anybody could make changes/fixes it isn't always an option for a company to have somebody jump in the code to try and get a handle of the codebase to make certain changes. If they had a contract with you, somebody who is intimately familiar with the codebase, then bugs and changes could be implemented faster and better.
