data analytics

As a data analyst, I am looking for help with several tasks related to data analytics. My primary goal is to assess and analyze companies data country wise. I currently have some data available, but I want to refine or supplement it further for my analysis. I am particularly experienced with using Excel as a data analysis tool, and would prefer if that software were utilized. I need assistance with data cleaning and preprocessing, statistical analysis and modeling, and data visualization and reporting. If you have experience with any or all of these activities, I am ready to hire you for this project.
