Lately, there's been advertisers posting and promoting their businesses on my non-profit organization web community. Instead of telling them off, I thought why not pick a sponsor or two?
The thing is, how much should I charge the advertiser to have a small banner placed on the category header like SitePoint has or sticky-post like WHT has? So far, I'm getting over 2 million hits for this month, and it keeps increasing every month.
This is new to me, so please bear with me. Any help would be greatly appreciated.
