Since it is only 1 corner, you might be able to use one or more floor jacks and some helpers to move it around. let us know if you need help.
None of the cheap car dollies are designed to handle much other than flat surfaces. Going up a driveway may be challenging depending on the surface transitions.
Yes harbor freight has them. A furniture dolly with a cradle or some plywood on it might work as well. You can also take off the wheel and put some fat people in the trunk and right back seat to help.
