It had been recommended by our GC and we were very happy with what they had to offer. They might be able to point you to someone who can do the installation for you.
FWIW – although I usually want the real thing, that doesn’t apply to molding. Real wood expands and contracts with humidity and temperature, causing gaps to open up between segments and/or the ceiling or wall (even when you fill the gaps with caulk that is supposed to expand, etc.) MDF doesn’t expand or contract, but it has to be painted (we always want white trim, so that isn’t a problem).
