BOSCH had nothing to do with the valve system...why would a shop need to be certified by them to work on it?
If the valves are too tight (which is how they tend to get over time) they can hang open and be burnt (eroded) by combustion gasses. If they are too loose you will not get ideal mileage, and will have some valve noise.
It does take some practice, but is not rocket science. Buy your self a feeler gauge, manual, and if you want the fancy bent wrenches (I have never needed them, but it would make the job easier) and dive in!
