We are looking for online advertisers!?

My business partner and I have just started what will be the next generation for TV also known as IBC (The Internet Broadcasting Company). We have our website and everything set up but we are still having an issue with people wanting to advertise on our website. Here is what our website looks like now. http://myibc.weebly.com. We are looking for people that exclusively sell items or products online (ie. website designer, web stores, and more). Can someone refer me or give me an idea as to how to go about getting these advertisers to come to me or somewhere for me to look to find them?
