Yeah, sales person! An introductory or formative period will be surely needed, possibly keeping you busy for a few months or even a couple years in order to have that job growing into you… but once you are at ease with the attitude, the techniques and the tricks, you will have a looooot of margin to accommodate any assignment as you like, because any employer will reward you for sales, not billed hours. Salesmen are the most paid people in any industry, and they often carry a leisure life through events (fairs, conferences, meetings) and networking.
