"Thank you so much Will for the work you did in our garden on Friday, grinding out the silver birch stump. We can honestly say after 5 plus years you are the first person we have come across who has done a job properly.  Hence the reason you were called in it seems. We were so impressed that you insisted on doing a proper job for us...that is a first! You cleared up and left it exactly how we would have expected. We really are over the moon.  Thanks again."
