I used to agree, but I now don’t. Enough input from a North American teacher can eventually get the accent acquired without the kid stepping foot in America. If for whatever reason that’s the desired goal, and the parents are prepared to pay for it, then it can be done.
You’ve been here long enough to have come across examples.
Obviously people pretending to be North American won’t work.
I’ve been turned away from schools for not having an American accent. This was a long time ago. No idea if that still goes on today.
Quite a lot, if you have specialist skills in the tech sector. A lot of big tech companies and start-ups in Taipei and Hsicnhu have an English “official language” policy in their offices. From my experiences, if you’re highly skilled and already in Taiwan (and willing to put up with crappy pay and a crappy work culture), it isn’t hard to find a job without knowing Chinese.
I’ve been turned away because they wanted a “neutral accent” or whatever that means too.
There is no transparency in Taiwan and sometimes job search is just a bit of a crapshoot.
Too much of a Texas drawl? 
Getting the discussion back on track to the OP’s question. So far we have:
Anything else?
Cook
I really think it’s a code word for “we’re looking for a white dude but won’t say it so we don’t look like racist hicks”.
English editing/writing, VO work.
Would LOVE it if we could listen to Taiwanese redneck English though. Pefect for a themed pub.
Gigolo
That only suits a particular demographic: young, tall, muscular, handsome.
If there are Taiwanese sugar aunties looking for fat, bald 55 year-olds with hardly any teeth, I’m all ears. Are there any fetish sites that I should visit? 
You might do ok if you dress up as Elvis. Make it a sort of personal theme. Elvis impersonator gigolo for hire.

If you have the right skills, and work experience then set up a profile on 104, maybe with the help of a Taiwanese friend.
People here actually don’t know that 美語 and 英語 are slightly different pronunciations and slang of the same language. I was asked once if I speak 英語 because they needed someone to translate for some British Governemnt official that was coming and the previous time they’d hired some Taiwanese Uni student who “only spoke 美語 and couldn’t translate well”. When I explained to this person (an English-proficient journalist with a PhD) that, besides slang, most Americans, Canadians, Australians, South Africans and Brits can understand each other with little effort, he didn’t understand what I was saying. He thought 英語 and 美語 were as mutually intelligible as 國語 and 台語. Since then I’ve met a lot of people (often parents and grandparents of preschool-aged kids) who ask me what the difference is. No one bothers to do the research. So cram schools capitalize on their “American English”, even when any native speaker of English from anywhere knows that the materials are strictly, only and exclusively worthless Taiwanese English
No, it’s more like Taiwan’s Mandarin vs Mainland’s. Exactly the same language but with slightly different pronunciation.
Not necessary to be tall and muscular. There’s a market for someone young, slim, tight and cute. I’ve been offered. Completely different market segment, though.
It’s not exactly the same language either. Variations in phrasing , vocabulary and spelling .But they are very close in reality. If you are talking the Queens English.
But English speakers have very diverse dialects. Non natives should make the effort to try and expose themselves to different accents.
