I have a website whereas I already charge my direct advertisers on a duration basis (per year).

I now feel that my website is capable of approaching some larger blue chip companies. I wish to charge these on CPC and with a niche website and a 468x60 banner space what would be the going rate and how do I charge for it? Do I charge upfront for a block of clicks or do I invoice monthly for the amount used?
