Web 2.0 Social Networking App

I need an app built that will allow us to add web 2.0 social networking web site user names and pw's store that information and then when we become a new member of one of these web sites we add the details to the app. Now, how the app needs to work is it will act as a tool for advertising to the sites that we have added to our app. We will login, and the app should provide a way for us to enter the data that the sites require to submit to, add those details and click publish. The app will then go through all of the sites we have added to our system and pulish the information that we just added. I know some site will require more and some will require less however the app must be able to just submit the info that each site requires. Each time we use the app we will be sending a new URL to each of the Sites we have in the database. The app will basically just be a way that we will not have to go to every one of those sites, login, and submit the details over and over again. An example of a site added would be say Technorati: The app will know our user name and information and when we choose to add a new site to be sent out to these sites, the app will require us to fill in say, Title, Site URL, Description, and Tags. We will enter those details and when clicking publish the app will know that techorati only needs URL and Tags and will take the URL and tags from the form we just filled out and add it to our techorati account. We will be happy to discuss more if needed but that should be it for this app. Serious bidders only and we have a Budget up to $300 All rights title and interest to this app will be transferred to us. You must also be available to update the app as needed and on a per project basis.
