Facebook Reach / Estimates

We are currently marketing Facebook ads through our telesales department. When creating ad's its possible to get estimates on the audience / reach of the adverts. We do not want to give our sales agents direct access to our facebook business manager, so instead we would like a simple page, perhaps designed with Bootstrap in the front end that somehow queries the facebook ads API to retrieve useful information they can provide customers based on audiences selected and locations they would like to be able display the adverts and of course the budget. We would like to know if this is possible and have some suggestions on what information we could give our sales agents from this and of course have a system built to do it.
