HI,
I've been running VJLoops.com since 2005. It's a small niche company that caters to the nightlife and entertainment industry although we do get customers that buy licenses for commercial projects and other applications. I try to cater to both markets but our primary focus is on DJs, VJs, clubs, festivals and special events. We have just over 900 artists and about 90,000 assets in 4k and HD. We pay up to 50% royalties and artists are allowed to set their prices above our preset minimums. Artists upload single loops and then have an option to create bundles or packs.
If you would like to send me a link to your portfolio I can take a look and tell you if I think it would be a good fit.
