Online Purchase Task - 2 minute project

Hi, This is a really easy project, but one I need a *really* fast turn-around for. All I really need is for someone with a credit card to go out and buy me a cheap subscription [$19.99] to an online library service. As a fee for doing so, I'm open to all reasonable negotiations, and you'll naturally be completely recompensed for the purchase via PayPal/Elance as well. As this is likely to be a monthly cost for me, I'll also probably be looking at using you under the same terms in the near future. I'd normally do this myself but am a student at the moment, so don't keep credit cards as a personal rule. As I say, though, the sooner the better: I need access to this material asap. Thanks.
