Ian Marcousé and A-Z Business Training are running two 3-day 'Starting to Teach Economics' courses, one in-person event and one online. You can get a 20% discount on the in-person event and 30% discount on the online event if you email marcouse@btopenworld.com.
If you aren't already signed up to Ian's Topical Economics mailing list, I'd really recommend it. The website is experiencing some temporary problems, so you can email him directly at marcouse@btopenworld.com
