I've found a website called BidForJobs.co.uk that claims to save a person money and time. Has anyone heard of it?

I emailed them to enquire about what they do and they said that it saves money and time by allowing consumers to post their jobs and await contact from various suppliers rather than phoning around and hoping to get the right one

I'm always a bit skeptical of anything that is 'free' but can't find anything on the site that would lead me to believe it costs anything. Has anyone dealt with them before?

Thanks
