I am doing an online photography course, and my current assignment involves using artificial light for a variety of portraiture shots. Apart from a flash, I don't own any studio gear.

Can anyone suggest where I could borrow/cheaply rent some equipment for a half-day shoot?

It looks like I'd need (at the most) 2 or 3 softboxes/umbrellas with lights, and probably 3 reflectors (although I could probably improvise with some white boards). Boom stands would also be a huge advantage but not entirely necessary.

It's only for an assignment, so I don't want to invest a great deal, so would appreciate any suggestions.
