Snow Maintenance . . . *SHSB
Almost nobody likes to #shovelsnow. We'd all rather pay someone else to do the job rather than do it ourselves. So, it's an easy #sidehustle to get into and it only requires a shovel and warm clothes. Think of it like this... everytime it snows, you get paid!
So, post a few fliers in your neighborhood promoting a driveway specials and your phone will ring off the hook with new business and they'll put your number on speed dial.
Upgrade this hustle with a snow-blower and a truck to haul it around, and you'll have more work than you can handle... Heck! You might even start a business! :o)
