"could you change the interface?"
"change the interface, offcourse but this takes days and'll cost you some more"
"days?! a few images? I only want those butons at the bottom to the top and make them more rounded and yellow...and the animation is ok but if you just place our new product in it, it would be great. Can't you do that in a few hours?tomorrow we have an important meeting and we would like to show it."
