Video Calls from Yard Signs & Websites?

Hey Real Estate IndieHackers!

I have been building ContactLink with my team, and we're looking at Real Estate Agents as a target market. Looking for feedback on whether this is a good market for us.

ContactLink lets you put a link on your website or social profile, where new clients can contact you by video call, voice call, text message, secure email, or book an appointment. You can put the links on brochures and yard signs via QR code or just typed out like mine is here:

I think if someone is looking to list a house, and Agent #1 has a phone number that goes to voicemail... and Agent #2 gets on a video call with the person right away... that Agent #2 is going to win and become the listing agent for the house.

For the Agent it's simple, our smartphone App goes "Ding" with a push notification and they click it to join the video call from wherever they are. Or they can use our App to send a text, email, or call back with a voice call. Or send a text with a link, "video-calling" the client. (Client clicks the link and joins the video call).

In a world where nobody picks up the phone unless they know who's calling... agents who are easy to reach and get "face to face" the fastest are going to win.

Thoughts?
