The reason that I made the post I did is that you are asking for a complete training course in system design, database design, program design, and script writing. While I am sure there are numerous folks here that could teach you all of that, and more, that is a pretty extensive education for a help board.
Why don't you post what you know about programming and design, and perhaps I and others can point you to reference sources where you can get the necessary basics to create the system you have described.
Can you program at all? Are you familiar with PHP? Do you understand the basic concepts of programming? Are you familiar with files, records, and fields? Do you know what an index or a key is? Describe normalization.
Finally, if one really is a newbie, one is generally better off starting out with very simple tasks to understand how things work. Build one simple script that accesses one simple table. Then proceed to the more complex stuff.
