Ok, I know this is pathetic but i cant get the timing right myself, i suck. plus i dont own a light or a tack, and my buddies sucks and i cant see mark very well, whine whine whine. Anyway whats a fair price to have a shop do it? guy i talked to said it would take about half an hour. seems right? Ive never gone to a shope before fore anything so i dont know what the going rate is for the stuff.
