Storage or Body Shop

Within the next 3-6 months we are going to sell our house and will be in a transition period for some time while we build shop and house on our property. I'm trying to decide if I'm going to store Duster or put it in a body shop. An option I wish I was ready for was to start the construction on the shop and put the car along with our household stuff there but we're not ready for that yet. Storage is expensive and hard to get out here, will cost around $300 per month for a 10x30. If the cars in the body shop the storage size needed will be significantly less. My body man does great work, did my sons firebird with excellent results but he's a terrible business man and we almost came to blows a couple of times. I would like to work out a piece by piece restoration so that the work gets done and I can better control how much I'm paying out, money will be tight as we have a septic and well pump to put in etc. Holy crap I'm rambling, any advice on a plan for the body shop (I'm talking with him pretty soon) or storage ideas, I'm bummed that I won't be able to work on the car no matter what happens....for awhile.
