What creative process should I use to make a killer explainer video that clearly conveys the need for our product? And who should I get to make it?

My company, www.ptengine.com, has a good web analytics/heatmap app that is currently desktop browser-only. The problem is, so what? There are dozens maybe more offerings out there. Their advantage is ease of use, affordability, and objectively the best heatmaps in the market. I'm trying to figure out how to make these videos and convey the values very clearly, because most people don't think much about analytics. The general attitude is, "I have Google Analytics, which is free, and it's Google, so it must be the best right?" *facepalm*
