for 3-7$ for an hour of work? I know everyone wants to focus on online methods, but I'll share my offline method, been doing it for years now; it's real manual labor though - snowblow/shovel/salt/clean off roofs. $25/hour. Depending on the size/scope of the house/yard it can be done quicker.It's a manual method (can't be automated) it requires like an hour a day
