What type of visa can I apply for in Thailand to conduct workshops and retreats?

The user is currently on a 60-day visa and wishes to conduct half-day workshops and weekend retreats related to the Wim Hof method. To do so, they need information on the appropriate visa and work permit options. Responses highlight that to apply for a Non-B visa, the user must start a company, employ at least four Thai staff, and have a minimum of 2 million baht in capital in a Thai bank account. There are no temporary visas available for such activities unless done in conjunction with an existing business.
