Hi there,
As somebody who specializes in comment writing and forum posting, I am confident I can produce high quality posts for your website. I know the importance of writing posts that actually add to the discussion and help other people out, which is why I have one of the highest repeat-hire rates among experienced freelancers on this site. I won't give a price since I'm still uncertain what kind of topics I'll have to write about, but once we discuss this further, we can perhaps talk about pricing too.
Sincerely,
Abbas
