Dave the contractor

I mentioned before talking to a contractor about my house.  His name is David.  He has a slightly gravelly, slightly nordic (NW) voice and asks all the right questions. We walked through my house, and he just wanted me to talk about it.  Seriously?  The first person not bored to tears about old house stuff ad nauseum?  About history and old beams and fires and how that all shows in the house?  It was all good to him.
After my list of stuff that was beyond my skillset --mystery leaks through siding, unsupported bathtubs, strange wood chewing insects eating the top of my fir floor and foundation work--he wants me to fix the foundation (as you all said I should do first).  My foundation is not attached to my house, a common thing in an old house.  Some posts are missing or taken out. The SW corner of the house is taking a slight tilt downward - gravity must be particularly powerful in that corner of the house, or, the 102 years the house stood without gutters did not do wonders for the foundation.
David and Sue, the project manager, are going to add/replace/sister all sorts of materials in my basement.  They are going to attach my balloon framing to the cement foundation.  They are going to have me clean out my basement so they can access everything.
OMIGOD.   Clean out my basement?  THIS is why I don't get this particular job done.  I have no closets in my house, my basement is basically my house size closet.  You know, the one that you shove things in when people come over and rapidly shut the door so it does not fall all out on your head?    The garage is not an option - it is full of construction materials.  My horse trailer is the only available covered protection I have and not near large enough.  I'll figure it out.  David says they will help with the moving....
