One thing I would add is that a good lab will also have LOTS of experience
(much more than you or I ever will) and can be very helpful in pointing
out where the problem areas are and even suggesting solutions; they
will have a long list of materials and suppliers to help. In the long
run, they can actually save a lot more than they cost.

For real problems, they probably will have a list of consultants.

Back when I did this, we probably would not have gotten FCC certification
without the help of the lab.
