Hey there,
This is really nice of you, but you might want to give a little more detail in your OP, explaining what you offer. Also, if you want to help people with language and grammar, you might want to make sure that there aren’t any errors in your message. As I spotted a few.
Yes, there are a few proofreaders on here, but we can always use more. There are FAR TOO many stories with bad grammar. As, I too, have started a proofreading thread to offer help to any that need it. 
Sorry, just offering some friendly advice.
Cheers,
Caliope
