Joomla - EasySocial Event Application

I need an application built that is installable into EasySocial for Joomla. The application would be specifically for the events section of easysocial and would allow event creators the ability to add sponsors to their event. Ideally, the event creator would have a drag and drop or "click to upload" logos system that they could quickly add the logos of the sponsors to the app. They would also have the ability to add a sponsor name and sponsor url to each of the sponsor logos added. Additional Features: - Event creator should be able to add more sponsors - Event creator should be able to delete sponsors - Event creator should be able to reorder sponsors Hopeful Features: - When an event sponsor is added to a particular event a stream post would be created within the event that would show the sponsor logo, name, website - Become a Sponsor Link that would open the EasySocial Message Box to create a message to the event creator
