Hi there!
I'm a fast writer and extremely confident in my native tongue - I'd be more than happy to work with you on finessing a final version of the copy. Obviously this will entail a bit of back-and-forth, which isn't a problem for me, I'm available most times of the day (I'm 2hrs behind SA time).
As I'm new to freelancer.com I don't have any examples to show you; that said, I worked for several years with Airbnb as 2nd/third tier customer service rep, which meant I was generating a lot of boilerplate text for responding to users, and helping with the copy for the website
I'm guessing this will be short, around 3 days' work including approving the text and making changes. I look forward to hearing back from you about this one!
Best,
Dan B
