It would probably reach for more firms and cost far less than mailing out CVs direct. However, Web browsing firms looking for prospective employees would need to know where to look.
This is where you come in, with an Internet job centre. Get people to send in their CVs and charge them for posting up a few brief details regarding their experience, qualifications and the work they are looking for.
Interested companies could then contact you, with you charging a fee for sending out each person's full CV. Try to group people so that companies can find what they are looking for quickly.
You can also offer a service to companies trying to fill a post, matching up people with their particular job requirements. This would be useful for firms without the time or equipment for Net surfing.
You need to make your site well known to companies. As well as advertising your presence via the Internet, contact the personnel departments of large companies and use mail shots to attract non-Net users.
