AppSheet app needs finishing off. Need someone with Google Sheet experience etc

General information for the business: GIGsoup music - online entertainment website (Music) Industry: Entertainment Description of excel work: We have an AppSheet app that is used by our writers to select albums to review. It works in it's basic form and is attached to a Google Sheets spreadsheet where it populates and selects its info. We need a few more bits added to it (i.e.: emails to be sent after a certain amount of time, finished items to be deleted etc). Anyone with Google Sheets and AppSheet experience would be welcomed Extra notes:
