Social WiFi capital portal software

My company provides marketing services for restaurants. We want to provide free WIFI access for guests in exchange for an email address or 'like' on the restaurant's facebook page and see the splash page advertisement. These are simular products: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] I need a simplified version of above products. 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 will see a splash page first after that they must ‘like’ his facebook page or fill-in their email. When the guest chose to login with facebook, he must ‘like’ the restaurant’s FB page and a post to his wall appears to say he’s 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 but still need to see a splash page advertisement. When the guest chose to login with email, his email must be added to our email database which we manage for the restaurant. We will create a separate form just for the wifi-login where the guest has to only fill in name and email address. Customers has a limited access time (Example, 1/2hr and they get Blocked for Example, 2Hrs). Limit the download speed. After he log in again he will see the splash page ( Advertisement server with third party ) You may choose any hardware. I suppose you would go for a solution like wifidog, something based upon chillispot or open wrt. If you accept this project: I would like to receive an estimate of the total price, an end-date. The 2 thing 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.
