Excel File Formula

I am looking for an experienced Excel expert to create a custom Quantitative Analysis file containing formulas and functions that will be used for data analysis. The solutions should be robust and support a variety of data types. The Excel file should not be restricted to any particular version, so that it can be adapted to any version of Excel. It should be able to support basic as well as advanced formula functions ( MAD & Naive Formula ). The key aim is to develop an efficient and accurate process of data analysis. The final output should be an Excel sheet that can be used easily for data analysis.
