Captive portal solution ( free wifi getting buisiness) - open to bidding

HI 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. These are simular products: [login to view URL] [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 must ‘like’ his facebook page or fill-in their email. (see attachment) 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. When the guest chose to login with FB likes or follow, 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. You may choose any hardware. Whether the requirement is at a café Chain or restaurant,
