Add New Design and Features to Twitter App

I need a new design integrated into Twitly dot com and a number of new features added (as part of the new design). * Design Integration - The design is currently in PSD and needs to be coded in VALID xhtml. I have designed the home page, main page and another inner page. Screenshots are attached. These are complex designs and will need a skilled coder to convert them. * Increase Tweet Storage - Currently only 100 tweets per user are stored in our system. This will need to be increased to 10,000. Knowledge of xml will be need for this part of the project. * Post to Twitter - As part of the new design, the users will need to be able to post messages to Twitter directly from Twitly. This isn't difficult but knowledge of the Twitter API will be a bonus. * Autoupdates - Currently the app pulls Tweets from Twitter every page refresh. I would like this changed to every 2 minutes via Ajax and without a page refresh. * New Contact Selection - Currently when a user wishes to add a new friend to a group they do so via a auto-complete search field. I want to keep this but also add a "click" to select feature where the user clicks on a users avatar to select them. Please look at the attached files and the Current [login to view URL] site for a better idea of what needs to be done. This shouldn't be complicated and bids will be considered on mainly price and previous work.
