If it's actually the kind of business that I have in mind that you're talking about, I think that amount is way too small to start a barbing shop business. Just renting a room might cost you almost that amount let alone buying equipmentsIt depends on the country you come from and the level of your economy. Here in my country, I think $100 is enough or even less. As long as you are able to buy all the equipments you need and rent a good place.
