On site assistance with excel and power point project in Hamburg Uhlenhorst

Hi, I am based in Hamburg and will have to complete Excel Sheets and Power Point Presentations (more complicated like project plans, org charts etc.) on a regular basis with some time pressure. I have only basic knowledge with Excel and Power Point and need somebody to show me on a regular basis how to advance to more complicated versions. Right now I have to complete Excel/Powerpoint for a board presentation next Tuesday, Jan 15th. I am based in Hamburg Uhlenhorst and would ideally work on site with somebody in my home office to get this polished. Online Sessions would also be possible but only my second option.
