Develop Wordpress Plugin

I need a wordpress plugin created that makes it easy for someone to backup their wordpress sites Including the widgets, themes and plugins to either Amazon S3 cloud servers or their own server or to download it to their desktop. Then Quickly and easily restore the site on the same server or on a new server with a different domain and database. There needs to be the option to set it up for automatic backups. The plugin will also seamlessly give the user the option of using Amazon S3 to host their media files. (pictures, video etc...) using the standard wordpress interface. I want a clean, easy to understand interface for this plugin. I like my interfaces to look similar to these: In addition to the plugin creation, I may need you after creation for updates. We can talk about that and work out a deal later. If this sounds like something you'd like to do, here's what I need from you when you reply to bid on this project: 1. I'd like you to let me know which of the example interfaces you like the best. 2. Your estimation of how long it will take to produce a beta version of this plugin. 3. I expect a once a day email letting me know of the progress of the plugin if I decide to select you. If you don't think you can do that, please don't bid on this project.
