REFOUND MY SOFTWARE

Actually on my personnal website that I use to do statiscal calculations, I already use software. The problem is that this actual software doesn't let me do exactly what I want to do and it cannot be optimized because of the language used (javascript) using a dhtmlx framework (with scripts not commented nor documented). That is why today, I need to refound my software. All details of my new sotware are documented in the attached file « How the software must [login to view URL] ». I think you would be able to win time (by using some already written scripts attached here) to developp new ones. Please, specify in your proposal the language, framework and logic you think to use to complete this project. ** Note ** I prefer to work with Freelancers who only work for themselves and their clients. Like that we can communicate all the day and it is also a way for me to be sure that the job is done fastly and carefully. I need scripts to be well documented and commented to explain the logic used. I need the scripts installed on the server to be sent to me by email too. ** Thank you for your comprehension **
