find someone with a team of horses, or do your roller method. I have
moved big stuff on ground using larger round fenceposts. six inch stuff
will do. Smaller doesn't work too good on ground. If you where on
concrete, inch pipe would do the trick. You can put it on rollers,
jacking it up with a car jack or handyman, have a dozen or so posts so
you can keep some under while moving the ones used, from the back to the
front.
