Firebase Help

Im looking for an individual experienced with Firebase Database. I have my database already set up. It all works fine for messaging, news feeds, etc.. What i need is someone that can help me add a rule to database that will know when a user is verified, like FB Blue Verification Badge. My app has the icon set up where it needs to be, i just need a way to tell the database that when a specific user is verified, to show the badge in the app in realtime. Willing to pay 50-100. Like i said the database is all set up, all you need to do is a few lines of code and help a brother out. Thanks
