Plus 1 for buying the tools and doing it yourself.
With the greatest of respect intended, there's loads of bike shops near me and only one guy who actually does everything properly.
The other shops charge top whack and do not observe basic things such as torque specs or checking the wheel bearings before a true.
In fact, I have observed many bikes where the wheels have been trued but not tensioned correctly and on another I had to use a length of scaffold pipe as an extender on the wrench just to get the lockring off a cassette.
I learned what to do and how to do it bit by bit after I felt guilty asking the bike mechanic to get the bike back to me by the next day (it was my main mode of transport) and I have never looked back.
