wheel sports, Quad expert or woody's would be the 3 that I know of. I would recommend woody's over the other 2, Dave did an awesome job on mine when I didn't have the right tools for my bike. or you could do it yourself it's not that hard and wouldn't take you that long. the scratch would be the tricky part, depending on how deep it is you can buff it out/fix it. if it's deep then you'll need to see if a Pro can fix it or if you need a new tube.
