Help in publishing my novel

Been writing my dark adult fantasy novel for three years now (it's manuscript only). I don't think i am quite qualified to edit and make it neat and clean novel. So i think I'll need an editor. Also i need to publish it too. I am quite confused how to edit, and publish my novel. How do i reach to publishing houses and qualified editors. Can someone help in making a roadmap or something. Whom to reach and all. I am very confused. Just a debut author who know nothing about market and publishing. I just knew how to write a story but I don't know what steps i need to take now and how to take them. 🙏
