I built e-commerce product for USA market. How do I find a native USA english speaker who knows to write good articles ? Who knows to record podcast with same article?
Well, the first thing to know is that there are 8 divisions in Marketing. No marketing professional operates well in more than 2 or 3. And PR is completely separate from all other divisions of marketing. Someone who is actually good at PR does none of the other marketing functions and vice versa. So, please dismiss any "specialist" who says that they can do PR plus anything else in marketing. That'll be a weak choice off the bat.
What you're describing however (write articles, podcasts) has nothing whatsoever to do with what PR is actually about (reputation). For articles and podcasts you're looking for a communications specialist and writer. You can specify that experience with writing for podcasts is desirable, but don't necessarily expect that the marketing person is the one who will speak. The subject matter expert is usually the one who should be speaking, though the content can be mostly scripted in advance.
The podcast and article should not be identical. The article might be a teaser to listen to the podcast, or it might be a takeaway after the podcast, but if you are just reading an article on a recording, there's very little point, and it would be a boring audio session, folks could just read the article.
For this kind of thing, my goto guy is Evan Specter. He's a clever and clear copy writer (and talented marketing strategist.) He's done audio/video production and organized webinars for our joint clients. He can do voice work himself or hire talent, depending on what's required.

There is more than method
1- Go to the freelancing website "Upwork I recommend" post exactly what you need and you will find applicants
2- Social media, make an ad with what you need exactly and ask people for CVs
3- Follow your competitors blogs and keep reading their content and check who wrote that. and if you really like one of them, you can offer him/her the job
4- Recruitment agencies / Websites. go for this as your last chance.
And for interviewing and selecting the right candidate. Always go for the experience, your experience. Ask them as a final step to write an article or record something about a certain topic.
I can do it but I am not a native of USA.
