Add Dimmer Switch and New Ceiling Light Fixture

Dear Mr. Electrician:  How do I add a dimmer switch and a new ceiling light fixture?  I want to hang a light fixture where there is currently no wiring.

I used a long, thin screwdriver inserted alongside the switch box to feel for any obstacles, such as pipes or wood studs.  A short piece of fish tape can also be used for probing into a wall.

I had to drill inside the wall to avoid damaging the crown molding around the ceiling.  A large hole was needed to fit the Milwaukee right angle drill into the wall to drill up into the top support plate. I did have to cut holes in the ceiling and the wall to facilitate the installation of a new 14/2 Romex cable to the new light fixture location.  I cut the holes at a 45-degree angle inward to make it easy to patch later.
