Okay, it's rare that I'd use an Uberflip example for your monthly inspiration but I think this idea is just so easy for anyone to replicate that I thought the value was just too great not to share. 

In our Ask the Marketing Expert campaign, we served up our own marketing team to give our prospective or current customers advice, ideas, basically a free consultation on any marketing related topic they were interested in. 

It was low effort and allowed our team and our company to show its stuff as an expert or trusted advisor. It built a ton of goodwill and is a great example of doing more with what you already have available to you—human capital. This worked especially well for our team because our target audience is marketers, but you could easily replicate this for your industry by being selective about the type of experts you chose. Maybe you strike a deal with an influencer or get your exec team involved.
