Those other clowns are just messing with you. If you have a chain saw simply cut it at the base or use snips to cut them at the very base. If they want the root ball up tie a chain around it and yank them out with the mower.
It would take me probably 30 minutes, and I would charge 100.00 to put it at the road or another 50.00 to haul it away. Also another 50.00 if they want the roots up. Shouldn't take you long.
