I need to know what level you are creating this presentation for as well as what country to include culture into the consideration. How many slides, what data do you need to be included? Do you have financials, what is the purpose of this presentation? Are you trying to sell something, persuade for new changes, gain a business partner or is it an annual or quarterly meeting? The likelihood no matter who does this is you will likely need actually 5 days total with 1-2 reviews before final touches. If this is executive level they may have different requirements than general management. Is there a pre-existing business format, will you need back up slides.
If all data is provided than it is probable to be completed within three days; however, i used to work for a VP who had 3 people working on his Executive level presentations and it took us an average of 5 days.
