There are not enough players in the streaming industry to negotiate. If you lose one you will not be able to make enough money from the other 2. They know this and will be able to low ball you. They also pay a flat fee up front based on how much demand you can prove for your product. Small studios cannot prove demand very well. You would be better off going straight to the physical distributors like RedBox and selling the rights to Netflix once you can show some demand for the product. Or, you could set up your own streaming site that lets users view the pilot for free. If they like it that can preorder the first season. With enough demand you can afford to sign that show.
