You might need NativeUi by Guad, Mod menu's didn't popup until I installed it.

RE: How To Change Outfits?
Any trainer should work, the jersey you linked seems that It will only work for Franklin. Since you have menyoo go to Player options-Wardrobe-Torso | Use the arrow keys or numpad to scroll though the shirts and stop once you find the modded shirt(If the texture is vanilla you can switch it by going down once to texture and scroll until you find the modded one)
RE: Looking to pay a developer who can convert 3D models
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 firstname.lastname@example.org.
Requests are paid separately from Patreon, and the price depends on the request.
and you only pay after I finish the work.
(I have never requested from him so I don't know how much he charges)
