What you want is a "pre-engineered" building (maybe one without walls, but it's still a building), so check the Yellow Pages for suppliers in your area, and ask them for references in your area, so you can go check out other carports/garages they've supplied. If you just buy a kit that has not been designed for wind and snow loads in your area, you're really not saving money. That phrase "in your area" seems to be a recurring theme, but it's a valid one. Also, be prepared to put down an adequate foundation to support it; resistance to uplift forces from wind depends in part on how the building is fastened to the ground. One reason for going with a pre-engineered building is that you can get them to design the right foundation as well.
Side note, wall and roof panels tend to be standardized at 3 feet wide, so if the dimensions work out to an even multiple of 3 feet it will cost less than if you go with other sizes where some panels might have to be cut lengthwise to fit.
