I am looking for an article writer in the aquatics industry, but I want someone who has experience per se, where would I need to look besides normal content creation services.. Michael
Maybe you could reach out to people who are in the aquatics industry, and ask them if they would be willing to write articles for you.
Either make a post in Content Creation saying that you need a specialist in that area, or try elance/textbroker/etc.
Here on DP you can definitely find them. Or on other forums... Most good quality writers can write about anything. And if they can't, they will do good enough research to do so. In my case, I have never written about that niche, but I bet that I could definitely surprise you with an article.
Yes, unless you require expert knowledge, a good writer should be able to come up with an informed, researched article.
Go to bidding sites like oDesk or Guru and specifically outline your requirements and pay scale. This is a great way to find freelancers and there is an accountability system (through eBay-like feedback) and escrow payment services to protect all parties. Good luck! Stephanie
