Wow that was a big long rambling....however, I do have some suggestions. Take them however you like.
You can have a cam studio without having the girls work out of your home. They can work from their own homes- basically like working remotely. You take a small % for the administration of the studio. OR you can have them work from your home.
Logitech makes very good, inexpensive webcams. You dont HAVE to use a video cam to give good quality cam shows anymore.
I recommend
streamate SO highly. They have both an awesome affiliate program and some great staff to help you set up a studio. They also have fantastic traffic for their cam models and PAYING traffic- not just a buncha freeloaders hanging out in the free chat area. Your models will appreciate that. Being bored waiting for shows is no fun, and the girls will burn out if they dont stay busy and make lots of money!
Other good options are
CamZ and
imLive. Both have good traffic, and good aff programs as well.
