Custom Gemini Gem or AI Engine

I need someone to build a custom Gemini Gem or AI engine that helps us put sponsor recaps together. It would pull data from mulitple sources and compile it into a document then create a designed recap deck in Canva. Will need to show work where it pulled all the data from with links so we can go look at where it came from. All information is tracked in Google Sheets. Pull sources from: Social Media Impressions from links (Meta, TT, YT) Website impressions (Google Analytics) Marketing Emails(GoHighLevel, Mailchimp) Demographics (Google Sheets) League Email Analytics (PostMark) Example Decks it would Create: Annual Sponsorships - https://canva.link/piu9m9kvb2mxdda Fundraising Event - https://canva.link/4mynspntffm4coc Virtual Event - https://canva.link/tvybbajwunzqzf6 Post-Game - https://canva.link/6tmxroc910gitqy I need it built in a way that others can use it - like I could charge per recap
