Website coding similar to ping.fm, onlywire

HI I'm looking to build a website similar to [login to view URL], onlywire and hellotxt. What I want is a website built which will post your contents to about 30+ websites from one location - Please take a look at [login to view URL] and see how they work - The user signs up for an account - after they have signed up and are logged in then they have the option to update status - [login to view URL] are connections to social media sites - sites such as blogger, WordPress, twitter etc - The user is then able to post to these accounts from [login to view URL] - so they make one post and it is sent to all locations - We also offer other ways of posting such as posting via email. Encryption and protection is a must - I guess some will allow api access and others will require username and password in order to post data. I will also need the coder to work closely with me and provide prompt updates - A list of all the accounts will be provided to the successful bidder I would like to see similar work you have carried out in the past - If not then I must be sure you can complete this task thanks
