Here is my two cents. As a pastry chef it's all about the bottom line. The end cost and what my profit will be. Therefore, if I were totem I would poll my members to see how many would buy cards from both Virtual girl and Desk babes of American models. Based on that outcome, I would then consider opening a studio in the U.S., thereby making the models fees more feasible.
As you can see I myself have over 1,900 friends on this site alone and some of them I chat with on Facebook. They have said they would buy more Desk babes cards if the girls were speaking in English. Here in the U.S., the porn industry has become a multi-billion dollar industry per year. If I were totem I would like to get my hands on some of that.
I would name the new cards Virtual Girls, Desk babes of America and charge three credits per card to help off-set the cost of the new studio in California where most of the new and well known models live and work, therefore cutting down on travelling cost as well. Also, I would consider the fact that the new models just starting out are looking for their first big brake in the business and will work for less money. I could use the profit from that to pay for more well known models and make even a bigger profit. Keep your cost low and your quality high end. I think you know what my vote is on this.
