253177 Calendar/Time PHP Script

Hi, please see my attached screenshot. Here's what I specifically need coded: Calendar that shows the Daily, Weekly, Monthly views Start/Stop Timer Enter Project/Hours/Notes etc, and log hours. Show the tasks for any given day etc. Basically everything on the right side of the screenshot. The left part of the menu is already built, its part of our internal login system, all plugin driven, easy to make a plugin for. Please let me know what it would cost just to do this, and then we will discuss finishing the rest of it. Need to know how long its going to take, and would like someone to start immediately. Thanks!
