Google Sheet Calculation Transformation

I'm looking for an expert in Google Sheets to assist in constructing formulas and functions, along with conditional formatting and data visualization. The specific tasks require advanced knowledge of SUM, AVERAGE, MAX, MIN, IF, VLOOKUP, and INDEX-MATCH functions, paired with expertise in color-based formatting, data bars, and icon sets. The ultimate goal of the project is to replicate a website calculator into a Google Sheet. Proficiency in creating interactive and visually appealing spreadsheets will be beneficial. Would prefer someone with experience in similar projects. Efficiency, skills, and attention to detail are a must.
