There are some websites that are well established in this industry but their pay out are not encouraging and that in turn is killing the get paid to view video industry.

I found links that might do the job for you though i have not used it personally https://www.streamingvideoprovider.com/pay-per-view-access-restrictions.html and https://codecanyon.net/item/paidvids-paid-to-watch-system/16458604

Good luck.
