Good day everyone!

I've been thinking about getting a soundtrack for my story, Archangels Guardian, or at least a soundtrack for the world it takes place in. I think it'll be a multiple-part soundtrack consisting of several sections, but the main problem is that I don't know any good music artists who might be able to take a commission from me.

Here's a good example of what I believe I'm looking for something similar to:

If anyone has suggestions I'd be willing to hear them!
