Hi,
I have a client who wants to create a site that will allow the public to swap things they have, does anyone no of an open source product or commercial that will simplify the creation of this site? some similar sites are:-

http://www.swapsee.com/SwapseeISAPI.axd

http://www.iswap.co.uk/home/home.asp

http://www.myswap.co.uk

Any ideas?
Thanks,
Richard

Looks like they are just auction sites?

have a look around at some of the scripts repositories like http://www.hotscripts.com - im sure you'll find quite a variety of different scripts which meet your needs.
