Probably just makes a mess, chose one category and go with it, and I would go remote worker, you never know if for an extension you will need to provide again the documentation, with your job (unless you stop) you are fine, with medical you may need to provide future appointments that you may not need for real.
If you were providing 2 courses both for soft-power maybe that would make more sense, but the distinction between remote worker and soft-power is clear and mixing them will probably create a mess for them.
The issue that you add these companies WITHOUT asking them to be there, they have no idea who you are, what you do with their info and so on.
Good business practice would be YOU contact them BEFORE adding to your website explaining the terms of the collaboration.
Instead you are farming around without asking and then, if they ever find out, you talk to them.
Great business practice.
It's like Airbnb starts to randomly add accommodations on their portal for free then if the owner ever finds out they talk for a collaboration, and you are nto Airbnb but a unknow portal, so it's even worst.
Safest thing is to ASK them, even if somebody did it last week, today they may woke up and change rules, maybe from 1 month to 3 or 6, send an email and you are sure.
If you get out and back in nothing happens, it's a multiple entry visa, you don't pay.
If you extend in theory you pay 1.900 Baht and you may need to submit documentation for your extension, but I didn't see anybody report an extension yet, there are just rumours, safest thing is fly out and come back.
Seems the interview is standard here then, well, I'm glad I got it after the long back and forth with documentation, but at least they are very fast replying, they asked me for more documentation in the morning, provided, then in the afternoon asked for more documentation, provided, then the next morning already asking for more, so well, they are fast.
