My current company lives and breathes spreadsheets. But we still have people, newbies and veterans alike, who aren’t especially well-versed in it. One thing I’ve noticed about these people is that they tend to work longer hours because even though they know what to do analytically (they can explain it to me using plain english), but they don’t know how to do it efficiently (or sometimes at all) in Excel. I am sure I can deliver what you need in excel.
