Automation Software similar to Senuke

I am looking to have a program created that works along the lines of SENuke. It does not have to ping sites or create spin content because it is not to be used for internet marketing. What I need the software to do is: 1) visit a directory of websites 2) bring this list of websites into my software 3) create an account with an automatically filled profile at every site on this list. 4) Complete e-mail verification process 5) revisit each site at regular intervals to update profile and submit new information. After submission to a site, a database needs to be updated with information about the site. I would like my software to be easily extensible so new sites can be easily added, automatically or manually, on a daily basis. I am open to all bids as I have no clue what this type of project would cost because I am not sure of the complexity of web scripting like this.
