Searching for someone to make a NPC Car seller/Car Inventory/spawner

Hello,

I am looking for someone that is willing to make a NPC that sells cars and where you can see which car you bought,
And can spawn them for my Gmod DarkRP server on RP_Evocity_v2d.
And is for me not to hard to add cars(and cars price) and edit the npc model, and location(With the vector and the angle)
I am willing to pay for it.
I hope someone here can help me out with this.

With kind regards,
Wesley Egbersten
