Independents Corporate Project

I have 3 excel files that have various bits of information that i need to pull into one 'FINAL' file. In that FINAL file there would be one "data" tab that would be the 3 excel files pulled together if possible into one data dump file. The additional tab would be contain customer info, contact info, address, phone etc & products purchased, unit qty's purchased, $ to date, brands with a drop down......all columns would have drop downs
I would prefernif we could connect & share my screen so i can walk thru the "ask, expectation" ....would this be possible? I need this wkst completed by the end of the night if possible.
