Light construction of new garden beds

In our Giving Garden, a grow-to-give garden in  Potomac, many of our fourteen  4ft x 25 ft raised bed boards need to be replaced. We are looking for a group to help us remove old boards and install new heavier pressure treated lumber in their place.  No real construction experience needed, just the ability to lift the wood, use drills and screwdrivers to anchor them. Very flexible on date and time.
