An elderly friend is in the hospital and has asked me to find someone (she

an estimate for installing a shower grab bar and a fold-down shower seat.

I'm not sure where to start ... for example, what kind of business does this
kind of work?

As usual Googling "Handicap access shower seats" will bring up enough
information to bogle the mind.
The skills required to mount a grab bar or seat do not require a
degree in rocket science. Unless the ADA device has the drill pattern
is spaced so that it coincides with the wall stud spacing some
additional blocking may be required. At the very least the installer
will need to be able to drill through tile and use corrosion resistant
hardware. Angling the grab bar will compensate for stud spacing.
Earlier posters have provided enough information to solve your
original problem.
