I finally can work on my book! But, what do I do?!

Recently, I've recieved an email telling me my application for a creative grant to write my book has recently been approved! I can finally work on my book full time! Not to mention that the funds I recieved is going to go towards hiring voice actors to voice in a audio book format along with paying me to create visuals for the book to!

Now, the thing is I'm caught in a conundrum. I am going to be going through with this audiobook but I do want my finished manuscript published. So, do I distribute the book myself through the socials or do I wait and send my manuscript to publishers first?

I'm aware of finding beta readers, maybe hiring an editor, but, honestly I'm not sure what to do.
