Coletive Sales App

We are a new brazilian coletive sales site. We don´t have much money I need a simple version of the App like [login to view URL], but with little diferences: 1 - When the customer click at the buy button, He will be redirected to the coletive Sales site. 2- No need to share the deal at facebook neather twitter. 3- No need the discurssion button 3 - the customer we will login at the app using the site acount. Don´t need the facebook intregration The budget for this app is $50 Thanks
