Seeking Google Sheets professional to find year-to-year trends across multiple sheets.

We are a startup nonprofit with the mission to reduce and eliminate violence across the world. We have an international, small team of board of directors. We need your help to organize raw data from Google Sheets into analysis, including trends and charts for a report and an index we are creating. Each year is a tab, and each tab contains every US state and multiple indicators for each. We also hope you'll consider both paid and volunteer opportunities with us in the future. Thank you!
