BanzaiMom,
I took a closer look at what you are trying to do and here is what I have come up with. RC Tech's Advertising policy at
http://www.rctech.net/pages/advertising.shtml outlines that to have your own forum under the Company Forum you have to pay a fee: Commercial Forum $30/month. Once that is done the Site Administrator will create a Forum for you that you can then create sub-forums for the different products that you offer.
If I can be of any further assitance please feel free to contact me.
Respectfully,
