Mechanics work what's next

Hi all, have created a game and it's been play testing quite well. I think the mechanics and balance work. Currently I have ai generated placeholder cards (based on characters i have previously designed) . I printed them and placed them over blanks. I've been tweaking wording etc . Now I'm happy with it.

My question is. What's next ? How do I proceed? I'd like an artist to take my cards and themes and give me their take on my ideas. Where would I find this?

Also how does publishing work ?

I really want to make at least 1 copy of the game, even for just my personal use would be great. But selling would be cool.

I'm very curious
