Social Wifi - captive portal hotspot for guests

We need the Social WiFi software solution that's been requested many times on this website, and as i could see you already developed for others. We want to provide free WiFi access for guests in exchange for an email address or 'like' on the restaurant's Facebook, Twitter and [login to view URL] These are simular products that we would like: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] For example: My customer has a restaurant. We want to install an access point where his guests can login to surf the web. But, prior to their access, they must like his facebook page or fill-in their email. (They should also have a possibility to log in with the Wireless password). When the guest chose to login with facebook, he must like the restaurant FB page and a post to his wall appears to say he sitting in that restaurant now. (or whatever message) On the second visit, or with another device the guest can login with facebook without liking the page again. We also need to collect information from social platforms about visitors who logged like this in order to have the database of previous customers, and also to have analytics and statistics as well as possibility to send information and promotions to customers. We prefer if the solution could work with affordable WiFi router hardware like TP Link (Open-wrt / DD-wrt) If you accept this project: I would like to receive an estimate of the total price and end-date, considering that you already developed something like this previously as i could see. The 2 things that are most important to me is good communication and reliability. Cut the complete project in 3 or 4 stages with a price per stage. In this way we both can evaluate the project and continue when all things work out as they should. I will not RELEASE MILESTONE upfront, but I will create milestone payment and release based on your performance and progress. Kind regards Marko
