Its the law of economics! If it would take you 20 hours of labor to put in the disc brakes, but in those 20 hours you can make more money than it costs to pay for someone else to do the work for you, then it makes more sense to work at what you do best and let someone else do the it.
You probably could have done the shocks, shift cable and sway bars yourself.
I'm pretty close to you on the mechanics level. Used to do it 20 years ago, but now I find making the time(when wife goes out) difficult.
I do find looking on the internet very helpful. Usually someone will post a pictured step by step way to do the repair.
Bottomline, the work is being done and the car will be ready for you to enjoy!
