Hi,
I can give you option to upload all pdf files in one go to the website and the links will be generated on website only based on week selection for the file. i.e. week 1 -> pdf1 link active and can be download. wee2 starts then --> pdf2 link will appear on the website.
I hope this is what you want, if you want something different then let me know. I am available online for further discussion and start working at the earliest.
Thanks
