As much time as is necessary for "Website Building". If you bring in your Quality (or "testing") people after the inception - you put them in a position of disadvantage (always catching up, and always behind) for the rest of the project; and if you do not empower them sufficiently you are just paying lip service to quality and crossing a line of the list -- and are very likely to endup like this project did.
