Data analysis

I am looking to hire a freelancer to help me with data analysis. The purpose of the analysis is to identify trends in my sales data. The analysis requires the use of Excel, which is the preferred software. I am looking for an experienced and knowledgeable freelancer, who can help find the insights I need in my sales data and generate meaningful reports. An added benefit would be familiarity with other accessible data visualization tools, such as a R or Python, to assist in furthering my understanding of the data.
