The past couple days I've been trying to find a way to make money on my custom ped in LSPDFR 4.3. After pain staking trail and error, I've actually found a way.
Using Character Swap, change your model to Michael, you will still remain as your custom ped but will now be able to make money through other mods. The only mod I've tested so far was simple jobs but it worked. I did this off duty, also tested going on duty and everything worked fine. I'm going to see if the cabs work as well using the enhanced cabs mod and I'll get back on that.

I turned google upside down looking for a way to do this so I hope it helps someone. lol
Happy RPing 🙂
Edit: I actually did run into a major issue. Trying to change outfits in my car through EUP screwed up my custom ped. So I would only recommend doing this off duty, you can switch back to freemode male or freemode female. I'll keep testing to see if there are anymore issues.
