Sq Ft Cost to Replace Deck?

Anyone know the sq ft cost to replace a wood deck (metro NO LA)? Pretty straight forward, approx 288 sq ft, railing, 1 staircase to about 4 ft.

Would be a quick job for someone with experience, just trying to figure out if it's worth it to do it myself with hauling the material in and out, the inevitable running back and forth to the Depot, etc.
