We need a website developed. About 10 public pages, and additional 5-8 pages accessible by the user after logging in. Another 5-8 accessible by the administrator. Website will sell a service and therefore need to be able to accept credit cards. Looking for a clean contemporary website style. Will be hosted on Amazon and needs be viewable on desktops and mobile devices (fully responsive). NO Wordpress.
Software will need to be able to link to the Google Adwords account of user using Google Adwords API, set tracking URL, and perform various other administrative functions. Software will then track each click through from Google Adwords.
What languages do you think should be used for the project and why?
