First of all, don't get hung up on titles. Do what you are really best at. Are you best a marketing or management? Hire a CMO, chief marketing officer to fill both roles or take the position yourself until you grow to the point of needing more "chiefs."

However, make sure you have a person who has a strong passion for marketing in that position. No sales = No money.

Best of Luck,
