Buying Buying whitehat adsense sites. $50+/month earning. Paying 6 x revenue!!

Hi there,
I'm buying sites which are making money through adsense.

I'm only interested in sites which are ranked through whitehat SEO.

Few things:
Site must be getting traffic from Google
Adsense earnings only
Will check the ranking, backlinks and other things manually so it would take some time so seller should have some patience
Will pay 6 x revenue. Like if the site is making $50/month, will pay $300 for the site.

You must provide me adsense screenshot for last 2 months and traffic screenshot for last 2 months.

Will pay via Paypal or escrow.
