Guess I explained it a bit wrong
I do not have a website. The website they want to make is not a membership site it is just a personal promotion website with a "Book a Show now/Join now" that leads to Streamate where I work.
The traffic they have is local, I live in Eastern Europe and they do fitness products on the domestic market their traffic is not for this. They want to open a "joint affiliate account" on Money Tree that is the program operator for Streamate. They would get 0% of my Streamate money but 50% of the Money tree money

If a customer joins through my site I get to keep the whole 35% from SM but at the same time I get another 35% from money tree if this particular customer joined though my website. They would get half of the additional 35% Money Tree money.
To be honest I can tell them that their cut is 10% and they will not care, the only thing they are interested in is the fact that regular customers spend money every day on models. They are stunned by this. They want me to record videos for them at least 2 hours worth every week for a long period of time and they will break them up in to smaller videos and mass upload with my websites watermark and create new traffic to my new website with this. Some of this traffic will join Streamate and spend money, this is the general idea. Their interest is in the data/feedback from mass uploading to tubes and social media they are dead set on promoting cam sites and cam girls.
The reason I am asking what a fair cut would be is that I do not want to offend people who could potentially help me in the long run. They have money and drive nice cars so I guess they know what they are doing. Somebody above suggested I make my own site or hire a designer, but the presentation I got from them mentions so much activities on their sides, I would never be able to do this myself nor half as good as they can. The website seems like 2 hours work from what they told me, the real work is in the constant uploads and everything associated with this, from converting the video to editing to watermarking to thumbnailing to categorizing to writing descriptions to actually uploading and then theres the analyzing the actual data. and repeating what brings more money. Respect to anybody who can handle this but I would rather jump out of my window than spend more time on my PC
