You might want to post the revenue screenshot or more proof of revenue. Many of us buyers here own several proxies. Checking on your daily visits, its almost 7pm here and your loosely at 1/4 the traffic you state. your average daily button views are at exactly 1148.2 according to proxytopsite .com: 1132.2 average according to theseproxies .com and 1134.5 average according to pwoxy .com
I know those are button counts from main page, but if those are main page stats and your counting stats from the proxified page then that means your main revenue is adbrite which pays better than bidvertiser but not even close to googles payouts. and 50$ a day ? you should specify the areas of revenue your speaking of. google on main page, adbrite on proxified page and other sources perhaps.
I'm not bashing your sale, but letting you know without adequate proof of your claims you wont get too many high bids here.
Good luck with your sale.
