Data Mining / Collection

I need a complete list of every Tattoo Convention in the world. I will spot check for completing by searching for a couple conventions and if they're not in the list / it's not complete. The data can be stored in a database or Spreadsheet. I'm open to other methods of collection as long as the Conventions and artists can be linked and the data can be exported for use in a database. Here are are the data types I need for each convention: - Convention Name - Start Date - End Date - Continent - Country - State - City - Address - Web URL - Contact Email - Contact Name - Contact Phone Number - Cost (How much per day / weekend) - Description - Large Image (Flyer / Poster / Promo Banner) Each of these items should be their own table / sheet that have links to the convention they are at. - Attending Artists (Name / Location / Shop Name / Website) - Attending Vendors (Name / Location / Shop Name / Website) - Sponsors (Name / Website) An example would be: Conventions: - #1 Ohio Tattoo Convention - #2 Norway Tattoo Convention - #3 InkFest Krakow Artists: - Bob Tyrrell / Conventions (#1, #3) - John Roberts / Conventions (#1) - Jime Litwalk / Conventions (#1, #2, #3)
