|A jumping jack will kill you and take forever. |
A plate compactor won't do a good enough job vs a jumping jack. They're better for gravel compaction.
A sheepsfoot is ideal, but you would have to find one and resell when done, plus maintenance.
A tow behind sheepsfoot is also a good choice, they are a pain in tight places, though.
I've used a skid loader roller for driveways and it worked well. If you went over the lift a few times, I'd bet you could get it to 95% compaction.
Another option, though slightly expensive is a Rammax sheeps foot trench roller. About the size of a 4 wheeler overall, but taller, they're heavy and work well for small is areas. They're usually walk behind, and newer ones I believe are even remote controlled. They work best if you can run them back and forth in a straight line, they don't turn very well in super small areas as they turn like a skid steer.
My vote is for a pull behind roller or a Rammax.
