realestate transaction data

I am looking to hire someone to help me collect real estate transaction data, specifically residential cash sales data from the USA by state and county for the top . The data should cover the past year. The data should include all the relevant features of the types sales, such as the address, date of sale, and price and how it was purchased. This data would then need to be compiled into a format that is suitable for analysis. I am expecting a comprehensive and well-structured report on the data that is collected, with an in-depth analysis and key insights. Thank you for considering this project.
