I would set up a SMS Marketing System for the business.
I would provide the business with their own app that customers can download.
From this app or portal website the business can send out unlimited text/push notifications announcing specials, discounts and the like. The business can do it or I can do it from my web portal.
In the business we will have a GEO beacon that would send a message to phones inviting them to join the sms list for discounts, coupon and more. If patron doesn't have notifications on, we would have a sign in the business that would allow customer to sign up via QR Code or on the web.
I would do local Facebook fan page marketing announcing the new app for the business so others can sign up and I would also run a contest to bring others to the app.
In short, I would be in charge of building this business SMS Marketing list and would like to charge a monthly fee for this.
My question is this: What else can I bring value and what if any could I charge a business to manage this for them?
