Creating a custom menu admin plugin

My site is avelim.co.il. The site is on Hebrew wordpress 3.3.2, using the theme Weaver 2.2.6 with many customization done by programmers. The site currently has 50 menus under "appearance". I expect to add more menus in the future. In this situation, the wordpress menu admin is not good enough. Navigating between menus and adding a new menu is difficult and you have to keep clicking on the top menu navigation slider. I need a custom plugin built that will add 2 features to the wordpress menu screen: 1. A separate button (not part of the top slider) to click "Create new menu". 2. A drop down menu to navigate through existing menus. The work will be done on a test site, and when successful done on a live site. The work should be dome in 24 hours after being awarded the project. Freelancer should allow 7 days for testing after he finishes his work, before getting paid. Freelancer applying for the job are advised to attach a screenshot of the requested menu admin area.
