I have a reasonably successful open-source project ( www.mediabrowser.tv ). The website is seeing over 50K unique visitors a month.
I would like to monetize some of this traffic by offering a "sponsors" section on the site and perhaps some sponsor logos in the footer.
What kind of a monthly fee can I realistically charge for this given I am getting 50k unique visitors a month? Naturally sponsors will be in the same "space" so by having a spot on our site they will be able to reach a fair amount of new business.
