Well, you can always charge less per hour, and people are more forgiving when service is cheaper!

You could also try an online, or paper course on computer repair. I am sure if you dedicated a few weeks study you could learn the basics. If you are quick and resonably intelligent you could most likely figure most things out. Also find a local established computer repair place and offer then the more difficult jobs. Maybe they will give a bulk discount, and all you have to do is take care of the customer portion. That way will not be as profitable, but you can satisfy the customer. That way you can accept all of the repairs and learn as you go.

I have a few friends that have owner computer repair business, and an a few that worked at them too. Seems like with decent customer service you could easily develop a good customer base (the crappy service I always get is the worst part).
