Build a Website

Hi, This is the type of website I need built. I will give you a list of around 30 university courses. These courses, some will have pre-requisites and co-requisites. The goal here is you will create a tree of sorts, that the user will fill in with the courses they have already completed. When a course is clicked, the courses that it is a pre-requisite to will open up. Once that initial information is provided, the next page will show details on that inputted information, such as number of courses completed, credits left to be taken, ect. Also, it will need to show the courses that the student can take in the following semesters, such as fall and winter. Then, the student can update those choices by swapping courses in and out. I will be posting a picture of what this should look like shortly. Also, a basic login system would need to be created, just to store user info in a sql database, along with the info of courses they have already taken. Feel free to ask me any questions, shouldn't be that complicated for someone who know php and sql very well. Let me know what you think and we can discuss more details.
