How to spawn as a GTA Ped

Hi im looking at for my server where people can choose either as freemode ped or be the peds that are already in the gta game (not addons) I dont want people using trainers but would be great if when they first join it gives them the character creation. Is there anything out there? Or how do I be a normal gta character like the ones walking around in the map. Hope I have made sense.

you might be able to add vMenu on your server and remove the other functions of it other than the skin stuff, you should ask here> vMenu v3.1.3 how you could do that
