If I was looking for someone to repair my PC, I wouldn't give a damn about if the person is a certified Powerpoint specialist or not. In fact, I would probably not choose said person simply because he clearly has no training/specialization in computer fixing, and just lists irrelevant qualifications that don't have anything to do with the services he's providing.
Edit: Your prices are way too high, noone is going to pay $20 for a simple virus scan.
Also, the "About Me" tab should be arranged as simple bullet points, imo. That makes it look more professional and easier to read. And slap a picture of yourself in there!!
