Forgive me for not looking at your archive before. How is it organized now? Usually helps to organize large amounts of data into carefully designed databases. Then you can code apps or pages on the front-end to make the magic happen.
The more time you spend organizing your data into a properly designed database layout the more success your project will have. You need to group the data into tables with keys and relationships. It takes time, but it makes the development end of the project so much easier.
