Hey, congrats! Not everyone has the courage to face the publishing industry even if their literature is highly recommended for public consumption. Because you already have your materials, the next thing you might decide on doing is to find a publisher who will be your retailer, publisher, editor and distributor at the same time - which is of course not that easy to find.
Writers like you have every potential to get started on a publishing career. If you are looking for self-publishing companies to publish your book, I know of a few companies that practically holds court to everything a book needs from getting you your copyright, size preferences, book cover design customization, layout consultation, copyediting and even marketing – at affordable costs.
Publishing companies now have all the resources to publish books with the same productivity and efficacy as that of regular black and white books you see in physical bookstores. Considering the fact that most books are in full color, you should choose a publishing company whose book’s are of the highest quality, bar none.
I hope I've helped :)
