L.A.
The best advice I can give you is to hire and interior designer (not a decorator) to help with major things like cabinets and kitchen layouts. We hired one when we were building and her help was immeasurable. She gave us tips and suggestions on things we had no clue about and we are so glad we used her. She designed my kitchen better than the cabinet company and made suggestions about things to include in the design. They have tons of experience and can help as little or as much as you would like.
we paid ours by the hour and consulted with her for the issues we were overwhelmed with. My husband is an electrician and is very knowledgable in most all the trades but he agreed that her fee was an investment in our house and the help that she gave us was worth every penny and makes out house stand apart from some of the cookie cutter houses in the neighborhood.
I had her go shopping with me to pick out tile (thankfully!) We consulted with her on colors and furniture layouts as well. She remove alot of the stress of choosing so may things at once. We did not want to make a mistake that we would have to live with for years to come.
Make sure if you do go this route that you hire a Designer with credentials (abbreviations behind her name) not a decorator. Anyone can be a decorator they do not have to have gone to school. Designers are trained in all the principles of building, lighting design, color, form and function and they can do sketches or plans to scale that can be used by your bulider or subs whichever the case may be.
One more tip is to go to all the house walks you can. You get tons of ideas from these houses and can also pick up names of designers. They also have lots of ideas for decorating. I still go to them to get ideas and kepp my decor fresh. Check through home magazines and cut out anything you really like. That way you have a folder with pictures of things you want and are not trying to explain the "fireplace" you want to a stone cutter whos never seen a Pottery Barn Catalog.
