EPOS analysis & summary (excel)

I need someone who is confident analyzing data and being able to produce clear summary and analysis
I need someone who is willing to commit to a team / zoom (or similar) calls as an initial project so there is a clear understanding and any questions can be answered.
Full support will be provided throughout via email, web chat , watts app and phone calls.
Project outline :
Retail business that has closed stores over the last 12 months
EPOS data YOY is indicating that total number of stores are not holding the correct levels of stock as the total number of litres and units is down yoy
I need to be able to prove or disapprove if the impact of the closed stores is having a direct effect on the total number of units being ordered on a weekly basis and the total Litres sold each week (sales out)
For privacy I will only share the documents once I have had an initial conversation
I require this to be completed in 8 days
