Real Estate Website Backend System

I am looking to develop a CMS that can be used for several real estate websites I have made. I will design the CMS with PSD files, and you will need to code everything, except the websites I have already made. Each CMS would need the following functions for each logged on user: 1. Site Editor - users may view their website and click on a text box within the website to edit it. I can code in a class name like <cms> for each text area. 2. Craigslist Ad Maker - I have designed and coded three html craigslist templates. Users will need to be able to select one of the three flyers, enter information into a form, upload a few pictures, and have the HTML code generated with their ad information. These ads then need to be saved under the user account so the user may get the html code for that ad again without having to retype everything. 3. Analytics - Users need to be able to see information similar (but not as complex) to what Google Analytics provides, but within the CMS (not leaving the admin website). An overall administrator login would need to be created that has the ability to: 1. Add websites to the CMS 2. Associate users to a certain website 3. Allows users to only modify certain pages of a website 4. Temporarily deactivate users from logging into the CMS system Feel free to ask any questions you have any!
