WTD - Pair of 700c wheels - 5 speed - cheap

I'm looking for a pair 700c wheels, with or without tyres/tubes. I'm doing Nightrider in June and my current wheels are tubulars and not suitable.
Also, current rear hub is only 5 speed so rear hub needs to be 5 or 6 speed at max, yeah I know, picky.
So, if you've got anything lurking in the back of your shed in fair, true, condition please let me know. I'm in Guildford and could collect if local.
Thanks
John
