I'm a small firm - 5 people. I work closely with an almost full time marketing guy. He helps me with social media, pleasing the google machine, getting our name in print media, and helping with taking care of clients and keeping them on drip marketing (and many other tasks). he's expensive, but I can see the results with getting more calls on bigger projects, and winning some of them. It took me years to get to the point where I thought I had the budget for it. Time will tell if it works, but I can tell that we are getting our name out there better because of it. Some of the staff also contributes to social media, but it's mainly Mr. Marketing guy. He's also an amazing photographer, which I recommend spending some $$ on proper arch photography.
