Your contractor should help you with that stuff...

We build houses and alot of the time we help the customer pick out appliances/paint colors/lights etc. Of course we always like it when we dont have to though. Just some advice... ask your contractor if he has any houses he can send you to see some of their work. And.. you usually get what you pay for so dont take the lowest bidder.

Dont change your mind once something is already done. they hate that. but its not free. And dont go hang around the jobsite everyday and watch how things are going. we dont like that either, we got work to do. lol.
