The qualifications for a business credit card have nothing to do with the type of business you're running.  Once you offer some sort of service or sell items for profit, have a tangible reason for needing a business credit card, and can provide the required information like a legal business name, a federal tax ID, business entity, and the number of employees you have, among other things, you can apply for a business credit card.  Your personal information isn't really important when applying for a business credit card application.
