Ummm not sure which website your looking at but we don't have a list of repair prices...
Charge more for some bikes like Hill dodger said.
Most of your repair price list looks OK but I would question what you charge for repairing a puncture on a chain cased bike (£28!)
Going toe to toe with LBS's you wont win if your repair prices are the same as you don't quite have the same market or the established customer base yet - go a bit lower than them, your labour is mostly free after all so anything above the retail price of the parts is pure profit.
I know a chain cased bike looks like a faff but if you know what you are doing with the case and the hub gear then's it's actually a quick win and not two hours labour - just watch for stuff like that as you don't want to compare badly with a shop that can undercut you on a job.
