Instead of launching a tube site with 3rd party content partners, why don't you:
- buy a Mech Bunny license
- brand this in your new tube domain
- upload all of your own tube clips that you have edited over the years
- use the banner space to advertise your own network pass membership and/or trials
- promote your existing cam platform
Once the heavy lifting of site design and content uploading is done, then the daily maintenance would not take you the hours that running and managing a tube site, with a content partnership program, would. As/when your editors edit a tube clip, you simply upload this clip to your own tube as you currently do with YouPorn, PornHub etc etc.
You may only have 2-300 tube clips, and only edit 1 or 2 new tube clips a week, but this is not about quantity, its about showing the quality and true value of your network membership.
To generate traffic, serve pop unders to your non member exit traffic. After all, this traffic has visited your site because they showed an initial interest, but for what ever reason, didn't buy a membership. If you had a "tube" that only featured your content, your banners etc, then that user will see the sheer size of your library, and the real value of buying a network membership with you. You could run 30-50% first month discounts on the banners, or trials. Remember, this was exit traffic that didn't buy a membership, but were interested.
So, rather than launching a new "tube" per say, and trying to improve on the user experience of existing tubes, and have this take up so much of your time, with little, if any, chance of making money, why not use the "tube" platform to make a glorified extended tour? It will make great use of non member exit traffic that you may never see again...
