Social media help finding projects

I'm not sure anybody can do this... But here's what I'm looking for.. I have a little small lawn care business and one of the best resources for leads are people posting on social media websites like Facebook local groups / yard sale groups and people that are on a site called nextdoor. They'll just ask for referrals and a lot of these groups and if you're not one of the first ones to see this then it's harder to get the jobs. Can anyone monitor social media for me and alert me of these projects? I need this on a monthly charge and an ongoing basis
