Is this a digital-only endeavor? I don't see any mention of physical product services such as pressing CDs & DVDs, printing covers/liner notes/etc. And what about marketing materials like posters, flyers and so on. There's still a market for that stuff, and it could be another revenue stream. Merch is also pretty big for some artists, you could explore getting t-shirts and hats and stuff printed. (just an idea, i've no idea if it's profitable, or more trouble than it might be worth)
