Chris,

I spec designs for steel buildings for the facilities I design. I've done all sizes with and without insulation. You can have a door anywhere you want if the skeleton is design correctly. You can get insulated and even sound attenuating walls. Anything is possible....but it's expensive. I have a few steel building manufacturers that I use. If I could have done it cheaper with one of them, I wouldn't have designed a stick framed garage for my own use. I would shop around and bid out the construction once you have decided on size and design. You can design the foundation and contract that yourself. My permit was likely more involve than your's will be, and I designed my foundation using PowerPoint! Find out what the code is in your case and design for it.
