Hundreds of PR3 Links Needed for 20 stores

We are looking for someone who can make hundreds of live PR3 links. These links need to be computer related and done with white hat techniques on respectable sites. Please bid based on 250 initial work for one store but this will be a on going project as we have 20 stores we want to do this for. Please note that this is a no escrow, paid on results project. Payment can be broken up into smaller amounts if desired.
