Again, a lot of rambling going on over a general question.
If you decide to pursue the actual construction of the garage, I suggest you find 3 contractors who have done other garage additions before, and are also favorably reccommended by people you know. Online reviews may also be reliable. Get a detailed estimate from each, with everything spelled out. In NJ they are required by law to provide you with start and end dates. The actual materials that will be used. They must also provide you with an insurance certificate that insures you and the work. If your home was built before 1978 and may have left paint, they must also provide you with a current certificate of lead contractor certification. The current licensing and lead certification can be verified online at the Consumer Affairs website.

For 576 sf of garage with unfinished interior walls and minimal electrical, you could expect to pay between $25,000 and $35,000. Your plan and permits can be approximately $3,000 to $6,000 depending on details involved. This also assumes that you are not doing any of the actual work yourself and the plans are done by an architect.
If your house have difficult sitework, involving a number of large trees or structures to be moved, or ornate features in roof shingles or highly detailed trimwork on the exterior, then the price would be expected to be higher.
