Farmmie... did you ever get this done?
I've been fielding quotes for this, one from an electrician, another from a light installation company and one more from a contractor.
The problem with the electrician, is if they can't get attic access (like a first floor), they will cut into your ceiling and won't patch, drywall or paint.
The light installation company, has a system where they are minimally invasive (sounds like a surgical procedure),don't cut into your ceiling, and will drywall and texture any holes (but you will have to paint).
I'm sure the contractor can do everything, but I'll see what he quotes.
