Completely agree with the sentiments regarding contact forms. Since most of the pitches you get through those come from Indian spammers, the default response when you receive a message offering content writing, logo design, web design or worse still
SEO, is to delete it. That means unfortunately genuine offers like your own get missed.
This thread is probably going to get you far more work than a day of pitching via contact forms, so I would say your time is better spent sticking to the forums.
So on that note, do you write sports content as well or do you prefer to stick to casino stuff?
