Hi AWC,
Here's my suggestions:
First, pickup one of our software licenses :
http://www.2Much.net. Long story short, it will let you broadcast your models to your own site + other websites at the same time, charge anything you want per minute, and use your own CCBill, Segpay, Epoch or Merchant accounts. If you use CCBill, setup a simple affiliate page and link to it.
Here's a screenshot of the LiveCamNetwork 4.5 Administrator program:
Next, contact Ero-Advertising.com, Juicy ads, Orgasm.com and a couple of others to buy some advertising. No need to spend alot of money up front. Buy slow, use Google Analytics to monitor everything.
Finally, take advantage of our mbase system to add more models to your site, and to bring more chatters to your model's rooms while you build your customer base from the advertising companies suggested above.
You can have everything set up in only about 4 days, and begin generating revenue right away.
If you would like to know more or see a demo of the administrator program please let me know.
Congratulations on your new studio!
