I need a long zoom lens: any help is gratefully accepted:

I have gotten a Press Pass for the upcoming Republic of Ireland senior internationals (versus Macedonia on March 26th and Uruguay on March 29th) at the Aviva Stadium in Dublin. I will also be attending all press conferences, training sessions and media briefings. I am wondering if someone out there might have a 70-200mm lens to sell? Ideally, the lens would be F2.8 and a reasonable price is also requested. Any and all assistance is appreciated.
