there are many bids for swoopo/madbid clones, and I've already seen some good attempts. I need one as well. It needs to be secure, first of all. Flexible, with all fields manageable with CMS. also, a possibility to automatically promote most bidded items to the top. I will need it translated to languages, translation will be mostly done by myself. For more info, please see other bids and learn swoopo/madbid usability. I need the site functioning perfectly under heavy load, no money will be released prior to that.
I'm looking for swoopo/madbid clone. I would go for ready solution, that is full AJAX and works fast, with good admin interface, easy to manage and have all options from original sites, plus some more - info on PMB
