Just throwing in my two cents here.
I'm a freelancer and I've seen some jobs that are like this. Some usually go for at least $4
per artist (that includes the discography and sorting, sorry missing link to proof). $10 for
300 artists, plus sorting and discography in high quality? Plus
high-speed seeding? No, I'm very sure no one will do it for $10.
At best, those will have to be separate jobs. One for the research and links, one for the discography downloading and sorting , and one for the seeding (bandwidth ain't free, except on Google Fiber).
At worst, someone will do it for cheap, but will not go through with it.
No one who PMed me went through with it.
Offer still stands.
I estimate this to be about $120-150 or more.
