Need and app for businesses (renters) to post their specials and coupons (billboard). It will be a single app with mutliple renters making postings to their billboard. Each renter must have priivate access to only their billboard and landing page. Each renter would have a permanent landing page for their basic information, which could include, text, photos, and videos. Each billboard posting would be posted for a duration (a day, 2 days, 3 days, etc.). Each billboard would automatically send a brief text message about the new billboard to those who have downloaded the free app.
Any renter signing up for the app would pay a monthly fee for their rental space and pay for any billboard postings on the app ($/day). There would need to be a shopping cart or whatever it is called to process their monthly rental (recurring, unless cancelled) and billboard posting payments. (The rental fee amount and the billboard posting rate could be different for each renter, and controllable by my administrative panel).
They should be able to update their landing page and post to their billboard from a computer or mobile devise.
I would also need hosting arrangements made.
Must ultimately be both for androids and mac products.
