WordPress Membership Area Development

We need to create a members area for our WordPress website. This will be used for uploading PDF documents for company staff. The main challenges have been outlined below:

1) Restrict content sections based on membership level
2) Protect PDF from downloads (we have a plugin for this)
3) Protect media and PDF files against direct link access (we have a plugin for this)
4) We need a search function that will allow users to find a PDF/File
5) We have 100's of PDF documents to upload, so we will need a simple process for adding new documents to posts
6) We already have a design (attached) that will need to be copied exactly

Due to the volume of PDFs, we would like a custom-built system, so that when a new PDF (WP Post) is added, it automatically shows in the main menu. Similar to how a featured thumbnail would function.

Skills required:

- WordPress
- (possibly Elemtor Pro)
- HTML. CSS
- PHP
- JavaScript

We need someone with excellent communications skills that can explain how the end product will function along with limitations before starting the work.

Successful candidates will be provided with a detailed brief before starting. We are on a tight deadline to finish the project and ideally would like to have completed with 1 week.
