banner advertising rates

[bheybugarin]

hello,

I have my own web directory focus in asian countries (and add more western countries).

I received an email and they are interested in banner advertising in my site.

Can you please give some advise what info should I need to give in this inquiry (webstats, impressions)

Also, the possible rates for banner ads.

I usually get traffic from free serps, ppc and exchange links that I have.
