The "Student or Non-Profit" option was created only for Students or Non-Profit Organizations so they can post projects at our site and receive auditions from the talents that are willing to work with them.
Taking into account that students and non-profit organizations are the only type of Voice Seekers that can have flexibility in setting the budget for a project, we only allow these two kinds of buyers to post a project that may have a lower budget than $100.
Please keep in mind that as any negotiation you would be performing with a regular buyer, it's crucial to negotiate the working terms before sending any final file, and this not only contemplates the payment (if there is a set one) but also the file format and final usage of the work.
Their rates could be pretty variable, and it is possible that a project could be pro-bono. However, it is possible there can be other incentives they are willing to offer besides crediting your name in their work, it all comes down to the negotiation you make and what you agree on.
If you are a new voiceover talent or you are looking into expanding your demo portfolio, this could also be a great option to keep in mind.
