Excel power query

I am looking for an experienced Excel expert to help develop a Power Query solution in order to collate and clean up my data. I have up to 100 Excel spreadsheets with forecast data for individual projects that I need someone to create a new query in order to efficiently collate and clean up my data. My main goal is to have a simplified, organized view of the data in order to make sense of what I have. We also have many other reporting templates that we require assistance with creation, ongoing support and customisation.
