I would recommend Terry Kaffarov, I pay for his Patreon. I say this models are great, here's his description: HI, I'm Terry and I make skins for GTA V, All my skins are fully animated, with facial expressions.
if you have a request, send an e-mail to terry_requests@outlook.com.
Requests are paid separately from Patreon, and the price depends on the request.
and you only pay after I finish the work.
Thanks
(I have never requested from him so I don't know how much he charges)
