I think you mean getting a business license.
A DBA stands for "Doing Business As". You can have up two DBA's for your business. My old church was technically, "Lighthouse Community Church." But they had the DBA of, "Lighthouse Community." Also, at my old job, we had two dba's, one for the company we aquried and one for our most commonly purchased item since people wrote checks for those two.
But you'll need to look into getting your buisness liscense.
