How much a custom PSD website design would cost?

Hi guys and gals,

I need a custom PSD web design for one of my upcoming projects. It will have 3 different page designs. I’m looking for a design like the ones in PSD templates section of themeforest. What I would like to learn is the average price range for this kind of works.

Can anyone tell me how much this kind of designs would cost?

in PSD format I can make one for you for only 150USD. If you want it in HTML format then it would cost much higher.
