You've given nowhere near enough information to get a final answer, but I can suggest next steps for you. (For background, I've worked as an author, co-author, editor, and ghostwriter on 9 books so far.)

Publishing is a business deal. You need to figure out what business services you need.

Do you even need a publisher? Do you need a distributor? You already mention needing an editor. Do you need marketing? Do you need retail agreements? Digital or physical? If physical, POD or offset, how many each of hard or soft, what size of print run can you afford? What business services do you need? Publishers have an awful lot of potential features of what they can provide and what those services cost.

Once you know the list of services you actually need, your favorite bookstore will have books that have listings of all the major publishers and hundreds of minor publishers, along with the services they provide and the specialties they work with. Work through the listings methodically, and talk to them all until you've got a deal. You'll also want to start shopping around for a lawyer at that point, both because they have connections and because they'll be working with the contracts you'll be signing.

Once you know what you need and have talked with your lawyer the first few times, you will be ready to start shopping around. It's far better if you have more money and are using the publisher as a paid service. That is, you pay them for the services they provide up front. It will cost you many thousand dollars but you'll require far fewer sales to reach profitability. It can be better to do an online plus POD service starting out if you're self funded. If they need to front any of the money there will be two phases to the deal, one phase before it's profitable and another after a threshold is reached and it's profitable. The exact terms will depend on your needs and the services they'll be providing. Before you sign with anyone, you'll need to work back and forth more than once with your lawyer to help you negotiate what's fair in the agreement. Good lawyers understand the costs of the various services and can help you get fair rates.

Just like publishing games, the more you need from them the harder your pitch becomes. If you need a lot of services the more it will cost you. If you're looking for them to invest in you, front you money, and pay for the books, don't expect a lot of money from the deal, and in addition your pitch needs to be amazing and you'll be rejected many times. If you've got the money to self-publish and are only looking for retail agreements that's rather easy.

2. publishing distribution for ebook
3. No hard cover or physical book planned at this time

For distribution of an ebook there are plenty of options. Amazon is the biggest with kindle direct publishing requiring little more than an html file and an image for the title. If you are comfortable with software tools you can use that same document to build/compile every other format out there. You're on the hook for everything else with the business if you go that route, but it can work well if you are marketing through your own channels.

There are many ebook publishers out there targeting specific platforms and specific readers or specific genres. I mentioned publisher lists, they also include electronic-only publishers. Understand the tools they use against piracy are also helpful since otherwise anybody with access to the file can make unlimited copies.

Be careful of contracts, you almost certainly want something that has a non-exclusive agreement since you've done all the work yourself already. If a publisher wants an exclusive deal they need to be putting quite a lot on the negotiating table.

4. making cover art.

Find an artist with the style you like and contact them. Often it's in the range of a couple hundred bucks, especially for ‘unknown’ artists when they're starting with something that wouldn't have seen the light of day otherwise. Artist friends are best, and asking around at local art schools is inexpensive.

5. Future Audio book production.

If you don't need it now, it's something easily done later.

1. an editor

This one is the most difficult. Skilled editors are amazing. If you go with a publishing house they'll provide professional editors, at professional rates.
