Automated Linking Scripts Needed

I am looking to buy scripts that will run on my linux server that will assist me in promotion of my websites. These scripts should be able to run on a linux server. I am NOT interested in bids where you and your staff will do a manual process to get links for my sites. I am only looking scripts that are already developed. I don't care what they do as long as they work to get links to my sites. This job is for scripts that you have already developed. Please bid and tell me what your script does. I am looking to buy several scripts and those with WORKING demos will be given preference.
