Hello gentlemen of SRP!

I was hoping that some of you guys might be able to help me out. I'm currently in college and looking for a way to earn money to go to school. However, with my certain set of skills and resources I'm not quite convinced that flipping burgers at my local diner is the way to go. I currently work with my dad on computers and I have done so since I was 13 years old. I always enjoyed working with him when I can, but I need a more steady (better paying) source of income.

Which leads me to my goal. Ultimately, I want to start my own computer fixing business as a steady source of income for school. A business for the customers where, if I can't fix your computer, you don't pay a dollar. Good and honest work unlike "the geek squad" that I hear people complaining constantly about. Most importantly, I believe that you shouldn't have to give your first born child up to fix your computer. So the prices will be reasonable.

My problem is that I'm really not sure how to go about marketing this business in ways that don't involve technology. I though about making a website and a facebook page to spread it around but the only issue with that is, if your computer's broken, you're not going to be able to access the internet.

So, to any of you business owners out there, how do you market your business sucessfully?
