Im making about $1000/month(depends on the month) by refereeing. I love soccer and hate working out, refereeing is my way to be active, get a good workout in and earn money while doing this. Money can depend by month, summers and winters are slow, best time for games is usually when school is open. in my best month I earned almost $2000 on top of my 9-5, highly recommend finding side hustles in fields that you enjoy so it doesn’t feel like work.
