I set up my own system a long time ago. Of course if I had a cut by a big Artist I would see if they work with a publisher and maybe assign the song to him.

See if your Artist works with a publisher. Basically if you assign a song to a publisher you are selling your song to the publisher for royalties. That is in copyright law. However check a publishing contract carefully and if there are things you don't understand find a lawyer to read it. Good luck.
