I just want to add that there are more than a few companies that are successful at organic lawn care. It has taken them years to learn how to do it, train employees, market it and be financially educated enough to pull it off. They do turn a profit and I know of several who have more than enough work to allow them to choose if they want to add a new client or not.
IMO, it is a goal worth striving for.
