Article submitter software

I need a software that submits articles to directories (50 websites). The software allows the user register to the directories (websites) automatically, only some letters must be enter for the user (captcha letters for exemple). The software requires that some fields must be filled as category of article, meta words, tittle of article, name of the author, article... Fields that must be filled depend on the website where the article is submitted. Every required field for each directory (website) will be filled by the fields previously filled by the user. So the data will be requested one time to the user. ## Deliverables The program I would like to have is a software that submits articles to directories. The number of directories (websites) will be 50. The software allows the user register to the directories (websites) automatically, only some letters must be enter for the user (captcha letters for exemple). The software requires that some fields must be filled as category of article, meta words, tittle of article, name of the author, article... Fields that must be filled depend on the website where the article is submitted. Every article is introduced three times (three versions that explain the same with different words) into the fields required into 6 differents paragraphs. The article sent to every directory will be a combination of the three articles, taking paragraph 1 randomly (choosing between the three paragraph in position 1), taking paragraph 2 randomly (choosing between the three paragraph in position 2)... The same until the six paragraphs are completed. Then the article is ready to be submitted to one directory. Every article follows the last step before to be submitted. Every required field for each directory (website) will be filled by the fields previously filled by the user. So the data will be requested one time to the user. A password and user name must be sent to the user when he registers to use the software, after the payment. The payment can be done through paypal, the payment will be requested every month until it is cancelled by the user.
