Couponic script customisazion

Hello, I'm Stephane from Belgium. I have build a project called GROUPROS with the script Couponic (Yii framework). I have to change something in this script and customize it. Here are the specifications for the [login to view URL] website -To make the language module is displayed with flags -To include language on the splash page module -To add fields in the registration module (company, address, post code, city, country, phone, VAT number) -To fill the content of the topics terms of use, privacy policy, about us and how groupros works. (content provided by me) -To make the deals found on the website facebook page. (You have to create the facebook page ) -To resolve the function of connecting through facebook (put right and display of the signout) -To display the menu on the right register (ex: [login to view URL]) -To make the menu to connect is on the right (ex: [login to view URL]) -Make the menu daily alert that opens to the top in grey, is also grey on the left and the right. -Do the module "you are a trader" in several languages as in www.superdeal.ma" -To solve the problem of accents What is your best price for this customization ? Best regards Stéphane
