Creating a custom plugin - filter posts in the dashboard b

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. Currently. in the wordpress dashboard, under posts, you can choose to show posts from a specific month. See for example [login to view URL] This is not enough for me. I want to be able to filter in the dashboard posts from an exact date - for example September 9, 2011. For this, I need a custom plugin built. The freelancer should send me the plugin as a zip file which I will install on test site. When the plugin is working properly, I will install it on a live site. The work should be done 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 posts filter by date admin area .
