Call your county clerk's office and find out if there are any licenses or permits you need to apply for before starting out. Although the majority of your business will be done outside your home, because you will likely be using a home office, you might find you need to clear this with your county or city first. In Harris County, visit the website of the county clerk's office and download the form for the registration of a business name. The options depend on the number of employees and whether you are an incorporated business--most likely not, at this stage.
