Right, that's because charging a really high fee for something that you don't know how to do puts you in the "dishonest" category very easily. Rarely do you want to pay some contractors to learn on your dime.
Hell, if someone is going to pay me to learn something new, I don't normally charge them EXTRA for the privilege.
I have seen this in action at big outsourcing firms. It has almost always results is poor relations afterwards.
