Gambling Forum Poster / Blogger

I am looking for a writer / blogger to create posts and on-going discussions for a US based gambling information web site with forums on: Sports, Sports Betting, General Gambling, Poker and/or Casino Games. Ideally, this would be an ongoing position which would increase activity and interaction of community members. Number and frequency of posts required will depend on subject and current events.

I have put a fixed price, but I would like bids broken out into price per post / blog.

Requirements:
1. Must have knowledge / interest in subject matter.
2. Posts must be written in a natural, unaffiliated way.
3. All posts must be relevant to forum and / or discussion.
4. Posts can not be Spammy.

Thank you for your time.
