Make website script customization

I would like to customize and improve a website maker script. You can try the live demo of the script at a "[login to view URL]" . This script allow people to make their own minisite without knowledge of programming. What I want to do is focus this script on academic world and e-learning. I will need the following features: 1. Adapt the script to spanish languaje (UTF-8). 2. Add a full texteditor in textareas. 3. Because of minisites will be dedicated to e-learning, teachers will want to add several courses containing several pages, then they need. a. Possibility to add several courses. b. Possibility to add several new pages (like "F.A.Q. Page" tab with "add new FAQ") c. Possibity to upload files like pdf to their user document folder (like images in "image gallery" tab) d. Replace the simples textareas with a complete text editor (like ckeditor or other) with the possibility to link /add images or files from their user folder. 4. If we are speaking about e-learning we need students to sell them via Paypal the online-courses front frontend template. 5. In the admin user panel they will need to manage the students of each course. In my mind I think something like student register and buy online course 1 > admin minisite allow new registered user to see/learn course 1. If he buy course 2, admin will alow him to make course 2. 6. In template's frontend I need a [login/register] button for students with a student area with his contact info, menu to course bought, and I don't know what else. 7. Because of minisites will be dedicated to e-learning, teatcher will need to create quizzes and student respond them (one by subject or one buy course). I thinks that is all. I am always up for suggestions if you have more ideas on this that can make it better.
