First off, a warning: I have no idea what I'm talking about, I just like to talk.
Okay. Commissioning a comic should be relatively easy compared to an entire video game. If you know the artist you want to commission, get in touch with them, ask if they're taking commissions, and get their rates. Be prepared to spend a bunch of money. Then, all you have to do is not get screwed by them, and avoid making them think you're trying to screw them. I have no idea how that part works, so maybe buy yourself a contract lawyer.
If you don't know the artist you want, go look around on hentai-foundry, furry art sites, pixiv, the boorus, or wherever.
Your comic length seems kinda ambitious, maybe? I remember one comic some guy--not on this site--made where the same two women had sex for something like 20 pages, and it kinda dribbled out over the course of--I think it was months. Don't remember. Also nobody was paying for it, I don't think. It was just a labor of love. But, hey, talk it over with your artist.
For the game, if you have wads of money to blow, you could pick a team on Patreon or whatever that seems to be able to actually get stuff done (good luck), then throw a whole bunch of "earnest" money into one of their current projects. Once they realize that you're serious about giving them lots of money, they might listen to you for their next project. Or they might not. Be prepared to spend a ton bankrolling the project, and for it to take forever. You'll probably want to try to nail them down with some kind of formal contract (unless you really don't like the color of your own money), although I can imagine that would scare most amateur teams away. Dunno. Never done it.
Actually to the best of my knowledge almost nobody "commissions" a game as such. Mostly game people just get their own ideas, produce a few prototypes, maybe make it into the late alpha stages, and then either get complacent or vanish into the ether (depending on how much money they've made so far).
However, you could maybe nab an artist or team who's made a bunch of Ren'py VNs if you approached them with an idea that they like. That would be short and sweet and wouldn't require much in the way of game design. I know there're a few furry artists who've produced more than one or two flash "games" (animation viewers), so maybe one of them would treat it like a normal commission? Furry artists LOVE taking money from people.
Anyhow, good luck. If you're some kind of lottery winner who has no idea what to do with the money, my early retirement fund needs some help.
