Creating a custom plugin to improve widget management

My site is avelim.co.il. The site is on Hebrew wordpress 3.4.1, using the theme Weaver 2.2.6 with many customization done by programmers. I have a site with 73 active widgets. I will continue to add widgets. In this situation widget management becomes an issue. I want a plugin created to improve widget management. The plugin should incorporate elements that exist in wordpress - in the widgets admin page, when you go to the "screen options" you can click on "Enable accessibility mode". This changes some of the ways that widgets are managed. Some of the behaviors are worst than the default behavior (no drag and drop, widget titles don't show" etc). I want the following features of the accessibility mode to be available with the default behavior (and not instead): a. The add and edit links b. widget configuration is done on a full screen (when you click on add or edit) c. Selecting the position of the widget by number of location. I want a feature added that does not exist in the accessibility mode - In each widget area in the dashboard the widgets should be numbered in ascending order (starting with 1). This will make it easy to define the desired location of a new widget. The programmer should send me a zip file of the plugin that I will test on a live site. When successful the plugin will be installed on a live site. The work should be done in 24 hours after being awarded the project. Freelancer should allow 10 days for testing after he finishes his work, before getting paid.
