A couple things that should be a addressed:

How many hours would these artists be working per week on a single project?
What would a regular offsite pay look like PER singular project?
And what would the artists get in exposure on DV? This should include a regular average.

All questions are important to address otherwise artists will be scared away without payment quotes of some kind as a lot of them are UNDERPAID or NEW.

Good luck to the artists applying.
