If you want to show me some directories that are free to post in I could possibly make a program that will automate it. I have built several marketing software like a Backpage poster, hi5 messenger and etc.
If you can send me the list of sites it was using I can make a program to do the same plus also solve captchas as well. Well the way it would work is use a captcha solving service where it would cost like 1/3 of a cent to solve each captcha.
