A site in the Bay area where you can build a house...What a lucky person! I would think that you would want to put the most beautiful and well designed and built structure on your property as possible. Given this rare opportunity, I would suggest that you find an architect - one who designs 'green' and is sensitive to the land. In the end, for many reasons, an architect can save you at least the fee that she or he charges, help you develop and express your own unique vision of home, and create a structure that will be a testament to conscientious building rather than another blight on the land. As an alternative, you may find architecturally designed homes on these websites: healthyhomeplans.com or architecturalhouseplans.com These plans have been designed and built for actual clients, and are offered as an alternative to standard stock plans. If you find a plan, you could take it to an architect or engineer to detail for your particular codes and conditions. I think there are a number of plans that were designed for sloped properties. An architect or engineer could easily modify the plans to work with your conditions. Good luck with your project!

Marble Palace in Stockton is very good and competitively priced. They work all over the Bay Area. Just Google them to get their contact info.

i agree with mines1919... you need at least three bids.. They should be delivered to you with labor cost, material cost separately.. you should have a clear idea with your allowance on your project is so you know what you have to live by and compare with the other. Looked at Kukun bidding.. it should do the job... i will be using it in two weeks.

The national average 5 piece master bath renovation starts at about 35K and goes up. Way up. You are way way low for this project. It also requires permits and inspections, and that the labor be done from someone licensed and insured. Which doesn't sound like he case from your chuck in a truck hack. He ain't a licensed plumber, that's for sure. Or electrician. And both are REQUIRED. He is far far to cheap for what is being discussed here. Scary cheap. As in he may rot your house down from improper work. I'd be scared to look at that kitchen work! I think your cheap little project needs to upgrade or it is not worth wasting money doing at all. No one actually puts in builder grade crapola a second time once they've lived with it the first time. It's what they dream of getting rid of as soon as possible. Labor is the biggest part of any job, so moving to better materials will not be that costly on that front. And you will get a much better return by hiring someone with better qualifications.
