You need to establish that you have a realistic budget and that you're going to spend it with the right contractor. Let them know you're qualified.

I imagine you might have been vague. Nevertheless, qualify out the ones you have already contacted and keep looking.

Do some searching online.

If you want to remodel your entire home you might want an architect for design first. Also, I'd call them not email them.

Make sure you get references and follow up. Have you read all the threads on here complaining about contractors? Another thing. Make a list of EVERY thing you want done in EVERY room. Communicate! Contractors tend to do a quick walk through and comment things like "Sure, no problem." Tell them what you want and make them repeat it back. Make sure everyone is on the same page. Get every quote in writing. Ask how many other jobs they will be doing at one time. Will you be buying the new appliances and fixtures or will they? We recently went through a whole house remodel. Our biggest mistake was hiring the contractor we used on a previous place a couple hours away. HUGE mistake. I think the advice here to GO LOCAL is best. Do call. Meet. Get references and make appointments to view their work.

Edited to tell you to be sure to check out your state contractor's licensing board to be sure their license is up to date and that there are no complaints.

Better to qualify that with "How did the contractor respond to any complaints made?" Sometimes a contractor will 'fess up. Other times there is no merit to the complaint. The existence of a complaint is not a reason to disqualify a contractor.
