I know this is pretty old but one of them could be good and that is yorkshirehour. A search on Twitter will show many people now running hourly hashtags like #YorkshireHour #DevonHour etc, then for that hour all business based in Yorkshire market their business using that hashtag. Could try reaching out to anyone that's running a Yorkshire hashtag or develop it and then try selling it.
Edit.. Just checked and some is running a YorkshireHour their Twitter name is @yorkshire_hour will need to check is it's still running though .
