EXCELL EXPERT

I am looking for someone with expertise in Excel to help me with a project. Specifically, I require assistance with formulas and calculations and need it completed within a week. I do not have a specific version of Excel or any other tools that I prefer to be used for this task. Therefore, I am open to suggestions for whichever tool the freelancer believes will be most suitable for the job. Ultimately, I need someone reliable to help me get my project done quickly and correctly.
