Create wordpress plugin

I want a wordpress plugin created. Here is a link to what I would like created, but I want to add another feature. [login to view URL] I would like to be able to choose left or right hand side for the sliders. I would also like to add LinkedIn to the 3 that are already there. I would like each slider to be able to choose if you would like to show 1,3, or 5 of the last messages, and to also be able to join you on that network.
