CMS for flash website

I have an existing website is built in flash. I have all the necessary source files. What I need to do is to modify design in order to add [login to view URL] mainly you will be required to deploy a constant management system to allow end-user to modify content with ease. They should be able to add pictures modify text etc. I hear that DRUPAL is great solution for this, but there may be others that you will suggest. I'm open to suggestions. here is the scope of everything that needs to be done: CONTENT MANAGEMENT SYSTEM Drupal/Jumla for the site text images and video HOMEPAGE revise layout to future images with links GBGB FINALISTS: list students and photos WORD PRESS BLOG CALENDAR : ability to submit new events and add this module to homepage FEATURED SCHOLAR THANK YOU NOTES PAGE and Home page module for it BECOME A MENTOR FORM PRESS KIT (PAGE FLIP) CLASSROOM: social interaction, Ustream TWITTER FEED PRESS PAGE: addition of categories, and Images. Potential redesign I estimate this project at $1000 and I expected to be completed by the end of the month. If you think my estimate is too high or too low please let me know.
