CKEditor Plug-in

Good day, I would like to build a simple module for CKEditor to simplify the writting mode, the user clicks the button to open a full screen area to write, similar to this: [login to view URL] I've attached three screenshots, the file with the name: "before start [login to view URL]" - this is what the user will see before start writing, when select the area and start writing the phrase will disapear. "writter mode_on mouse over the gray [login to view URL]" - is when the user has the mouse hover the grey area or near the grey area, this way the user see a couple of options that he can use to write as well some other features like the number of characters and words. "write_mode when [login to view URL]" - this file shows when the user is writing in the rectangular area, the previous paragraphs will degrade in color and the actual paragraph will be black. This need to be done using CKEditor last version with jQuery module. Please let me know the amount of time you need to complete such project and the amount you are looking for this simple plug-in. Please also include your previous portfolio. Thank you
