Job: Griffin system like World Of Warcraft for medievalRP

Hello, to start sorry to ruin your so beautiful language ^^

I am currently working on a medieval RP and I would like a system with an NPC or, for money, the player can go to a place on the map that I can choose on a gryphon.

There is already a WOW griffon model that is usable,

This is my first "job" so tell me if my request is feasible or too complicated thank you.
