npc RP scripting

Hey, I’d like to add NPCs to my darkrp server which when you press e to them, it opens a buy/sell menu for the players to navigate. I’m assuming this is fairly simple, and would like to request a mentor or someone to do a quick script on this.

I have 2 years knowledge in C#, basic C++, VB(if that helps) and know quite a lot of e2. I know many of you will should that lua is easy, but I still need someone to help jumpstart my experience

Money will be given if script is awesome :smiley:

I’ve tried those DerpRP buyer which can be found

and

I’m looking for NPCs similar to those, just with a menu.
