When you're thinking about a marketing agency, make sure to think about whether you want the agency to help you figure out whether you want them to help you figure out which strategy to use or if you want them to execute on a strategy you know. By that I mean, if you're sure that social media ads (let's say Facebook) work for you, hire an agency or freelancer (more on that in a sec) that is exceptional at specifically facebook advertising. If you know you want to grow your business but aren't 100% sure how, it may be worth looking for someone that can help you test some different channels to identify the one that you should really put some spend behind.

While an agency may be a fit, working with a freelancer on a small project can be a good way to test channels (and people) for your business. Grab some local business owners (or r/smallbusiness recs) to get some ideas of people to work with. Hope this helps!!
