My SubScribestar page is https://subscribestar.adult/naughty-netherpunch
There is no reward tier for custom commissions on subscribestar, but you can send me a private message there to discuss your idea, so that I can say if it is possible and what it would cost.
I think you're also on discord? I remember seeing your name there. You can send me a pm on discord as well.
