I'm not quite sure what your actual classification is as a consultant, but you can look into the LTR to see if you qualify.
If you do, it's one of the best visas around right now and really the only visa in existence that says it's okay to work remotely in Thailand.
Otherwise over 50 will work just fine for you. No one needs to know you're working in Thailand. Thousands of people work remotely and while technically illegal, the laws that govern work in Thailand haven't been updated in decades and that makes remote work more of a grey area. They don't ask and you don't tell.
