Still, i think we need a logo, with importance to site name "BizHat.com" than image of the hat. Look at Yahoo and Google, the logo's are nice even with out complicated graphics.

I have searched google for logo, but could not find any good designs, if i see some good one, i will post the link.

I made few logo's in GIMP, i don't like any of them, still i will upload them and give link shortly.
