You would probably need a license for it . One thing that I have extensively read from fellow traders in the US, is that its hard to sell bitcoins without the license.I also don't expect you would get a serious and completely accurate reply on btctalk, so would suggest asking a lawyer rregarding this.
Absolutely right which you would really need a lawyer first to ask regarding on the regulations of your government when it comes into this kind of business specially it involves on crypto knowing that most governments doesnt like it. Having a consultation first with a lawyer is the best possible initial move that you should do so that you wont risk yourself into any trouble when you do plan to build that kind of business. I would say this thing would be profitable for you but would really still depend on the interest or the number of people on your place do know about bitcoin or crypto.
