Job: Help/Guide with making a Prop Hunt Server

Hello! I recently created a small prop hunt server with some mostly small maps which gained some players while the server was bare. I wish to expand more on it with some of the addons on this site but also need someone who can help but also explain just a little bit how to do things, so I won't be left clueless in the future.

The prop hunt addon I'm using is: Prop Hunt: Enhanced by Lucky.

(Willing to discuss budget change if need be)

What I wish for:

1. I want to add a "battle pass" like event, so the players may obtain skins while completing certain challenges.
2. Allow faster downloads for players
3. blacklist most of the default player models
4. A guide on good "gmod store" addons to integrate into the server
5. custom taunts to add
6. Replace some of the weapons that the hunters have
7. integrate a good chat system with colors and also have announcements in the chat
8. a way to link both the workshop collection and donation store in the server
9. general advice!
