Excel Guide

I am looking for a freelancer to create an advanced Excel guide with a focus on formulas and functions. The guide should be in the form of an interactive workbook with step-by-step instructions to help users develop their Excel proficiency. This workbook should include visual elements to aid in understanding and comprehension. The guide should also include practical exercises and examples to supplement the lessons. The final deliverable should be easy to follow and understandable for the target audience.
