Dock Launcher for MAC OSX - PPC and Intel

I need some one to develope me a dock lancher app for MAC OSX This must be and icon of the dock from where i can open many types of apps, documents, files and so on... The apps can be selected from a list (wich will open applications folder, and then click on checkboxes or maybe 2 windows drag and drop or with buttos to add or remove ) The rest can be selected just by draging the icon to the app dialog window. There must be an option to creat categories, and then we can add links inside and outside the categories (categories will work like folders...) program must have a mac stylish interface, be very clean and easy to use. Installation must be a single file only. here's an example of something like i want: [login to view URL] have questions? feel free to ask whatever you want. Please show me other MAC apps you have developed before. I dont mind selecting a new coder, as long as he can show me good work from the past, or he can build an experimental prototype before i accept the bid. Happy bidding thanks
