KingFish, Saw your post on getting footings, foundation and slab installed and that is what I do for a living. Licensed, insured builder in St. Marys County for over 20 years.....because of the size of the structure (>300 sq. ft.) and because you are installing a permanent foundation, you will need a permit for the project. If you would like another bid, call my office at 301-373-2109 and set up an appointment for us to take a look at the project. Sounds pretty straight forward, and the bid you have right now may be a little high unless htere are some other circumstances (i.e. steep slope, difficult to access, etc.)...thanks!!! Tom
