Just use sawzall and loppers, cut out what you need to. Then knock out any really high spots with a pick axe or shovel if you need to maybe remove a half yard dirt in trailer or pick up truck. Dump a couple yards soil on there and seed it.
Most trades will do whatever and leave a mess or damage and just leave it. But because of our line of work it’s always expected that damage is fixed before your job is considered to be done. But I still see paver and walls, concrete etc jobs where they leave the yard a huge mess.
