The design for the bookshelf addition and new vertical shelf dividers (size based on items selected for shelf).  I've also included an example of a picture light.  This one is plug in, so the carpenter or electrician would drill a hole for the cord.  I need to know from the electrician what type of light will work best - hardwired, plug-in, or battery.  We'll either need to have a remote for them or have a wall switch added.
 
There would be two, one centered above each of the existing bookcases, where the X is indicated on the drawing.
 
Depending on the size and style of the light we select, expect $100-$200 each.
