I know you mentioned not wanting to run with one of the main guys however I am going to give my two cents from someone who used to run cam from her own site up until recently. I know it can be a pain in the ass however if you are running a website it is very difficult to do a lot of cam per week (which you will need for member retention) I would stick with someone like camz which is who i used to go through. I believe they only require 2 hours a week and you get everyone elses streams to use as well so its well worth dealing with a few of the chat ass holes in order to keep your members. Also you dont have to deal with any of the high bandwidth cost for running your own stream.
Hope that helps a bit
