Drilling out concrete

[angepower 10]

Can anyone advise how much it would cost/if it's possible to hire someone to drill out some small concrete walls in my garden?

 

Just moved into a new house and the previous owner seemed to love concrete in the garden- they've put some small garden walls round a veg plot and concreted them into the ground. I want to get rid of the walls and any concrete underneath and it's really ugly!

 

I think with some brute force and a big hammer we could probably knock down the walls ourselves- but its still going to leave whatever concrete there is in the ground that was holding them in place which I want rid of

 

Any advice appreciated?
