The reality is that if you dont have quality leads that is a consequence of Lead generation, lead capture, lead Nurture and Lead fulfillment.

This app has been a game changer for managing the business.Beyond that I use my scanning app to digitally capture documents, applications, receipts, etc.

After deciding to mail the next important aspect is lead capture.

The bigger issue is what are you sending, how are you capturing and what system are you using to manage data.   

The reality is I can enter your market tomorrow with direct mail, PPC, TV, facebook, etc and capture a really good return.

Can you capture in seconds, if not dont try as it tends to distract?

I would start with an area your interested in targeting and blast the neighborhood with a mailer, then hopefully some responses and you are able to capture those leads. 

Posting a video, captured on my phone and posted on FB is not in the best interest for my business.

if that's all you need, set up a Podio account (Free for up to 5 users), create a "Contacts" app with fields you need to capture the info you mention, and use Tasks with reminders for making sure you don't lose track of anything.

Also, for lead capture I use the gentleman above me @Michael Quarles CRM call-text.
