I'd advise going to the local GUM as our first port of call if you need them quickly - perhaps advise them of the nature of the work and explain why you'd need so many. But do look at the Freedoms NHS shop as they sell them in batches of 144s and they're very cheap, I think as low as ?11 for that amount. I don't know where you could get 100s of free condoms other than the GUM but for the prices of the NHS Freedoms shop it really isn't a huge outlay when compared to their usefulness and the hourly amount we get paid.I'd definitely recommend pointing these part-timers in the way of SAAFE too just so they can maybe have a look around and gain even more useful information
