Hi,
You can find my academic and professional background in my profile.
What it doesn't say there though, is that I'm a huge football fan, and that I've been following European and international football closely for more than 15 years now. I play(ed) in various fantasy leagues (Premier League, Eredivisie, Champions League, La Liga) as well, and I'm currently contracted to write Fantasy Premier League previews (transfer targets, etc...) by a British client.
As far as my bid is concerned (for 10 articles of 500 words, as per your request):
Price: $125 for 10x500 words (rate of $0.025 per word, to start)
Time: Considering two articles a week, there should be no more than 48 hours between you providing me with the task specifics and me delivering the final result to you.
Work: The articles will be written in native-level English, and the content will be 100% original. I actually enjoy reading and writing about football, and it will further improve my own knowledge as well.
Contact: I'll provide you with my email and phone number (if you wish), so that I'm always available for questions or comments. I usually answer within a few hours, at most!
I don't know how to attach a file to a Freelancer bid, but naturally I'm more than willing to provide you with some samples of my (previous) work. Just let me know.
I hope my profile interests you, and that you're willing to consider my bid,
Take care,
