This sounds good and it kinda crossed my mind that having a 5 star reveiw for businesses on Steemit would be a great idea. I'm glad you're working on it.

This is what I currently do now for local businesses. Help them with their online reputation. The videos get syndicated on Youtube, Facebook, Twitter, LinkedIn, Daily Motion and Tumblr. Take a look at the video

If you think that I can help please let me know.
