How much should I ask for a 20x24 complete garage building?

I have a 20x24 (10 foot high) garage with a 16 foot sectional door with remote Genie screw drive opener in Mohave Valley/Needles area that I need to sell... And have no clue whatsoever as to how much I should ask for it. It'll be ideal for somebody who needs a pre-made garage and that has a way of putting it on rollers and moving it to his place and set it down.

That way, he doesn't have to go through the hassle of building one, since it is already built.

Any ideas as to how much I should ask for it, is sincerely appreciated.

Here are some pictures...





Thanx a bunch in advance...
