Steve, what is the goal of the social media presence? Clients for you or clients for your clients? That could be important. My first thought was, "Of course! Images = Pinterest!" But in the case of your remodeling company, if it's male owners, well, they probably weren't cruising Pinterest to find a photographer. May have been, but Pinterest users are overwhelmingly female. But like you said, their clients might be searching Pinterest for remodeling IMAGES, leading to clients for them. You mentioned realtors in the past, if I remember correctly - where to realtors hang out? On LinkedIn? On FB? Not sure how to find this out.
I have different social media approaches for different audiences. Pinterest is personal and some dissemination of good information for work. I am driving a bit of traffic to Twin Cities Gluten Free through Pinterest, which is big for food photography. Twitter is networking for my paid job. There are TONS of techy educators hanging out there.
Here's another thing with social media - you can automate it. You can set schedule FB updates and tweets and pins. Then, you just go to town with your own site and connect it all up and you don't have to do a ton of posting, though there is the monitoring of comments.
Just some thoughts, not real advice. It's easy to be overwhelmed by all of it and I'm figuring it out as well.
In my own business news, I have decided to put on a one-day craft retreat on October. Have booked a space. Will keep you all updated.
