Looking for someone to break up concrete

Portland OR

Description

We have an 8' x 12' and about 5'' thick slab of concrete in our backyard (see picture). The only access back there is through a gate. We're trying to get rid of it- unsuccessful with a small jackhammer. We don't need anyone to remove or haul the broken up concrete. We just need someone to break it up into small enough pieces so we can move them with a wheelbarrow. We can offer $300 if anyone has any interest/ability to help with this job. Thanks!
