This is when a Professional Organizer comes into your home, does a total home evaluation, sets up a plan of attack that you agree with, (including what items to use, the budget to stay within, storage items to use etc.) and then percedes to do the organizing, following your guidelines.
This is used often times by people that have very rugged work schedules or that for one reason or another just do not have the time to do it themselves. A plan is set up, as close to the client's lifestyle as possible, taking into consideration various variables. The time that this is going to take is discussed and a plan is set in motion. The amount of hours that the organizer may work in the home, what will be attempted first etc.
