Do you have camber plates? If not then your camber isnt adjustable stock...you can change the camber slightly (About a Degree) using the slack in the stock bolts. But thats about it.
The first thing that you need to go do is get a second opinion. I went to an Alignment shop where the guy tried to tell me that I had possitive camber on one side but just looking at the damn rim you could see that the camber was negative. Anyway after you do that. If its still possitive then check for somthing being bent...you can get camber plates or bolts, but I would check for anything thats bent first.
