Quick, easy job.
I would do it for around $130 and then try to up sale replacement with some nice mulch and decent replacement with something that would look nice. I would go slow and easy pulling them out, no need to risk damage to home or foundation saving a few minutes. I have a tractor but would not bring it, just a logging chain, and 4 wheel low and slow. Bringing the tractor just adds extra cost for me as mine is full size, wish I had a bit smaller one. Figure it would take me about half an hour.
