You guys are doing really good stuff for the indie community, thank you for that! I also found out about dSound and Choon through you! I personally can't offer anything like you are looking for, but if you are interested in perhaps looking into partnering with/adopting more blockchain music services, check out SounDAC/PeerTracks and perhaps Voise (they should be beginning their artist onloading soon from what I understand).

Also, I haven't searched this specifically, but mix/mastering engineers or graphic designers involved in the Creative Commons community could be really good people to contact.
