Startup Idea: Automotive Industry Messaging and Video App

Startup idea to develop an easy-to-use automotive industry-specific messaging and video app that allows salespersons to send text, videos to customers who inquire about vehicles while preserving individual privacy by preventing other salespersons from seeing each other's texts.

I work in the automotive industry, and I would like the ability to send texts through an app, with videos,to customers who make inquiries about vehicles. I would also like this organized in a way that doesn't let salespeople see each other's texts.The video needs to be compressed to easily buffer, but also look good. fInally, this has to be EASY to use (say, three buttons or less) as most car salespeople are older. car texting software.
