Job: Need of a custom script

We need a system in DarkRP where players can buy and win different types of skins, sweps and other. 

The player can buy the following items with darkrp money in a menu:

* Any specified swepsor weapon

* Premade skins for vehicles (William's Car Dealer) (like this addon: https://www.gmodstore.com/market/view/texstickers-texture-customizer)

* compatibility for integrating more addons

The challenge is to modify these addons to specifically grant access to items, and at the same time not creating any big overhead or laggy garbage for the server.

All of these items can be unlocked after playing for an amount of time. After that, you can buy them and get permanent access to it.

You can only get very special items after winning them. This can by achieved by (for example daily login) which increases your chance. These should be one unique item every week. (randomly chosen or predefined)

Everything combined in one window that can be opened by the players.

This job should be completed by the end of December.
