Custom File Upload SocialEngine Plugin, Similar to Box.net

I'm looking for a skilled PHP developer to create a custom plugin for SocialEngine. This SocialEngine plugin will allow users to upload files into folders (like [login to view URL]), and be able to share those folders’ links, as well as being able to preview those files before downloading them (like zShare). This plugin will be very similar to Box.net. This is just a generalized idea of what I want the plugin to do, there is a bit more - I'll give those who I feel are suitable the whole document explaining in detail all the requirements and features that I'm looking for. You should be familiar with SocialEngine and how SocialEngine plugins work, as well as be available for potential long-term to add new features to the plugin and fix any bugs that may arise with the plugin. When replying to this project, please provide your portfolio or an example of any work that you have done that is related to this. And please mention the word "cookies" in your bid/comment/PMB so I know you actually read the full project description. The price I'm willing to pay for this plugin is negotiable, as well - it all depends on whether or not you deliver what I'm looking for. If you do a good job, then I may even give you more - for a job well done :)
