Electrical Walk Through

On Tuesday, 23rd I will be meeting the builder, Mark Porreca at the house to walk through and make decisions about the placement of TV, phone, power and light points through the house.
EEeeeek
I don't want to do that on my own at all!

I have started drawing it up to get an idea what I have in mind. I don't know where to put computer lines. I don't know what kind of light I want in my bedroom. I can't decide on the kitchen
Oh woe is me :P
