Hey Diane - Ive had a similar situation, I have a Visailian that was/is wired and I decided to scrap all the wiring and start over again. What Carrie said is great advice, Carl has great information and products and also there's tons of You Tube videos on doing your wiring. Ive been afraid in the past so I planned out each room with lighting possibilities and I decided its better to over wire than under wire if you know what I mean lol. This way if you change your mind you have options and aren't limited. Carries suggestion of a ceiling light is the best way to start tho, this way you get a feel for it and you can do more and youre more comfortable.
Keep us posted and let us know how it goes!
