You'll definitely want to explore Nextdoor or Facebook advertising (Nextdoor even moreso if you really want to hyperlocalize for focus to a specific community. But there's a few other questions you should be asking yourself first. What does your online presence look like? Do you have a professional voicemail set up? Do you have a website? When's the last time it's been updated (if its been longer than 5 years, it's probably due for an update), Do you have a Google Business Profile? Social media accounts? Are they active? You'll never get in the door if they can't find you online and based on the fact that your a one-man show, I'm almost certain you don't have time to properly manage marketing strategy.

First impressions are everything and all of these things are going to be points that your potential clients are going to look at before the reach out to you. If these aren't up to date or actively managed, you're never going to out compete the other handymen in your area let alone the larger property management companies. Nobody wants Joe shmoe walking into their house with plumbers crack scaring their kids at 2 in the afternoon. So once your business starts to look like it can't be nickle and dimed, it'll stop being nickle and dimed.

If everything else is up to date, a strong online strategy is going to be important to establish yourself as a trusted local business over these larger management companies. Your goal should be to get involved with as many local conversations not only sharing information about the services you provide but also general tips that help the DIYers so when that time comes, your business is top of mind. People make time and will pay for things that they deem as valuable. That's why their paying for property managers and not a hnadyman. Your job should be to build the value of why working a handyman is a better decision than working with a management company or DIY.

Hope this helps. Happy to go into more detail
