Do you know Skin Video ? It's a multi-category video site with some good voyeur / hidden cam content too. Their system allow you to link directly to a category page or a search result, so you can make a gallery of a specific niche and direct the link to that specific content.
The company is solid, I've been using them for many years and it is still one of my best sponsors. Link:

There are also many other microniches you can promote, that make easier to make sales and payments.
I'm advertising other sites in that category, most of them are single site sponsors (some verotel, some ccbill and some with their own platform that means you need a minimun amount of sales to get a payment). If you have a look at my voyeur page you can find all them there...
Hope this helps.
