Database of conferences

I am looking for someone to create a database or an Excel spreadsheet, and if possible, to host it online free of charge(This is not a requirement). If hosting isn't free, please let me know.

However, my primary requirement is an Excel spreadsheet or SQL database containing information on conferences in the following countries: I want to be able to click on it and my colleagues to also click on it.

Places to search for this conferences could be Google, 10times

Period to look for
November 2024 to December 2025

UK
USA
Canada
Italy
Spain
Australia
New Zealand
Germany
Belgium

The conferences should be at least 2-3 days long—no one-day conferences I repeat again no one day conference. Additionally, please exclude expos and focus solely on international conferences. Conferences related to African development, healthcare (especially cancer), education, environment and net-zero, and international development are all acceptable.

Thank you for your help
