i want to create a small web platform that receieves user from ads on google, etc band registers their profile information. The platform must have the following features: A CMS to manage content on Home Page (where people land from ads) and a few other pages that describe the service A user registration form developed in the following way: - first registration info (such as username, and mobile phone number) to be requested in Home Page. - sceond step registration which requires use to submit email address and basic profile information (e.g. birth date, city of residence, zip code, etc.) then once user has completed secodn step he is required to verify the mobile number information The system is connected via API to smsgateway provider like clickatel. Once user submits information in step two, the system will send an sms with random generated pincode that user must put back into the webform in order to complete and verify his registration. If the registration is successful, the user will land on a third page with a form where he can provide further information User can also update his profile and unsubscribe to the service The system must have an interface capable of describing the registration statistics: where the user came from, where he stops in the registration process, etc. The system should also have a backend access to the DB information look & feel and key creative guidelines will be provided by us
