Wanted, Web load tester - Cambridge (UK)

We may need to make use of a web load testing expert for a week or two. The task will includes writing some automatic load tests and telling us how many users our system can cope with etc. The work will have to be done on site in Cambridge (UK), as we expect to learn how to do it ourselves by working with the person.
If the person has used lots of different load testing tools so match the better, as they can then help us pick the tools.
Can anyone recommend someone? Please email me at "inneedofspeed at ringrose dot name"
(Anyone that phones me or email me at my normal email address will disqualify them selves from getting the work. If we go ahead I will of course let anyone that looks hopeful know the name of my employer and all the details.)
