Do you have access to more than 500 staff?

I will need you to get your staff to each download a piece of free utility software from our website, over a 1 week period. You'll need to have access to more than 500 members of staff who are capable of achieving this ideally. The idea is to 'stress test' the website with traffic in a shirt space of time in order for us to iron out any server issues before general release in 6 weeks. I'll provide more details prior to starting the project or if you have any questions. Please ask if you have any questions. Thanks!
