Joe is right. In the marketing sector branding is important.
You are your own brand, make it recognizable, known, and desirable. If you go into business without any kind of business experience or knowledge you have to knock on the door of experience. You need to be visible. If you live in a large community you might want to print some fliers and put them on cars in the parking lots, parking garages etc.
The bottom line is that people need to get to know that you're around, what you do, and you need to be in touch.
And then, of course, you need to be really good at what you're offering. If the competition is better than you, what chance do you think you have?
