Wow! It would depend on the size, density and whether there are thorns......and of course, the root mass underground. In addition to the time required, there's also the time spent loading and hauling away and dumping the trash...there will be a lot. I have a hedge 2x that and I suspect 4 strong workers could get it out in a day. Two to cut, two to stack and then all 4 on the roots. It would be a long, hard day for them. Cost......no clue.
