Hi Alexander,
I love the sound of your project, and the YouTube examples you posted are the sort of music I love working with.
I'm a full-time professional music performer, producer, composer, educator and educational author, sheet music transcriber/arranger/editor/engraver, working mostly with mainstream publishers along with private clients. Most of my recent work via Freelance sites has involved audio production (principally here and UpWork where I've also seen your advert!)
I have uploaded a demo piece to my portfolio that hopefully matches the style of music you're after - this could easily be looped to 2 hours total playing time.
If all this sounds good then I'd love to work with you on further audio.
I hope to hear from you soon.
Kind regards,
Alex
