Hello Kansas Chic:
My sympathy goes out to you and your bank account. I hope you can find a Certified Remodeler in the Home Builder's Assocation, who can take care of all your projects. A parade of specialists would drive you up the wall, make you mad, not complete their work, take the money and run..... do you get my drift?
Some of the things you will need are:
1. A written contract
2. proof of liability and worker's compensation insurance
3. An unbiased inspector to verify completion of the parts
4. Checks made to the remodeler and their supplier (if the supplier signs the check, they can't come back on you to collect).
I am happy that you are willing to keep us posted with words and pictures; it should be fun.
