The Gnome said:really, that is so overpriced via the skill it takes...no offence...and your 30 day 5 minute touch up is kinda silly via prices...there is no way that is worth what you charge...
Then do it yourself. I'm sure you can do things like OVH ERGO levers, have the tools to pull and install bearings off Campag UT and PT cranks, can swap springs on calipers, press in headsets, build wheels, overhaul king hubs.
Don't forget $300 cutting tools(6 of them) and a couple of truing stands(decent ones, not an old fork with pipecleaners zipp tied on it) and a tension meter and presses and pullers(4 of them), the last PT bearing puller I got cost $275.
I'm sure you don't use a piece of wood and a hammer to install cart bearings into $400 hubs or a $150 headset. That bearing press I have was $400. I'm sure you know all frames are not prepped when you get them new(or old) and can properly prep the whole thing, have a full set of sharp taps.
Start a service bike shop, charge what you think is 'fair', but be sure you have a store front, and insurance, and utilities and a phone and don't forget the variable expenses like the 2% for CC fees and all the other 'costs of doing business'. . You 'may' want to pay yourself the below minimum wage per hour rate also that most bike shop owners pay themselves.
And taxes, yes, you pay lots of taxes. Like SS tax, workman's comp if you have an employee, and sales tax. Nothing more fun than a big month followed by a slow month, still gotta pay state and local sales tax(8.31% here).
have fun.
