I like the idea, but I hate the business model. I have a deep mistrust of services that make money from people who are in desperate situations. Charging unemployed people for a service that might help them get a job is an ethically grey area.
The fact is this sort of service would be awesome if unemployed people could access it at no cost to themselves. If it could be run with either government money (to improve national employment levels) or corporate sponsorship (so companies get better CVs) then it'd be very useful.
