Advertiser for my Blog

[kornmyk]

Hey BBHF member's YOUR SUGGESTION AND IDEA'S NEEDED..
I am planning to run a website
that will provide user's free download's like freebie section here
in this forum ..

I know it's not possible to use adsense
on such site's, I am looking for direct advertiser's for my site..
How should I approach the advertiser's or what should be traffic
value, how much unique visitor's should I drive
to get direct advertiser's advertise on my blog??

Any idea's?

Thanks guy's...
