'Digital Nomad' - Teaching English online?

[Little Butch]

Wasn't sure whether to put this in the travel forum or here...

Basically, I love to travel. I love my job as an Arborist too and have worked abroad with it but the countries I'm interested in right now don't have a big, if any market for it. So I've been looking into the whole 'digital nomad' thing over the past year or so.

I'm in Thailand currently and have met plenty of English teachers who work both online and at schools.

I've never taught before, don't have a degree but I have a tefl cert and a level 3 diploma in Arb which weirdly may count for something? (Purely because it's a certificate from England)

What's my chance of landing a job? Best way to go about it, where to look etc?
I'll need to get a decent laptop, earpiece etc..

Ideally looking to setup in a Spanish speaking country so I can continue learning the language. .

Any advice would be much appreciated!
