Help Redesign My Gradebook Website!!

I am the owner of www.gradebookpro.com. It is a website for teachers to input student grades. Although it is fully functional, there are many improvements and fixes I would like to be done. Firstly, the design of the website is very simplistic and lacking any visual appeal. Your job will be to add a touch of simple visual appeal. Nothing fancy, but an improvement in visual appearance would be nice. Secondly (and more importantly), your job will be to review the current coding and implement the changes and fixes that I've thought of. I've attached a file which lists the major additions and bugfixes I'm looking for. Please see the attached "gradebookpro.txt" file for an idea of the scope of my requirements. Although this is not an exhaustive list, this list encompasses nearly everything, but is certainly a rough draft at the moment to give bidders an idea of the complexity (or simplicity) of this project. If you have any interest in pursing this project, please let me know! I am a teacher myself, so please know that your work will be well-utilized! Please send me a message if you have any questions or concerns. I am looking for a finished project by the end of July so that I can start the new school year with a new gradebook!
