Yard and forest work

We're looking for somebody to help with general upkeep on our 40 acres of land. This is all simple work needing nothing in the way of special skills: raking up pine needles and leaves, piling slash into slash piles for later burning, using a string trimmer to clear grasses around the house and outbuildings, etc. This is not a full-time job; we're thinking maybe two days a week or equivalent, at times of your choice. We will pay $20/hour.
