I am a marketing consultant based in San Francisco with more inbound requests than I can handle. I am well aware that I could make this an agency, but I am not sure that my margins would support the work. How have other solopreneurs scaled their consulting practices?
The normal answer to this question is simply increase your prices until you start losing clients, hire staff, or spread the love and get a piece of the action.
I you form associations with other marketers you should charge up to 30% according to your role. If you have a small roll you could charge as little as 5-10%.
