Reskin and add additional features iOS and Android app Unity3D

I've recently purchased a project called Jelly Garden from Chupamobile. [login to view URL] I would like a re-skin of the app. I have a few ideas of different themes, however I'm also open to different ideas and I I would like someone who has experience mobile application development to be able to discuss this further upon selection (I'm not going to publicly ask for ideas) I would like to discuss in more detail with the chosen developer. However, prior to any work being started, you will have to complete, sign and return the following: - Non disclosure agreement - Work for Hire Agreement I would like to replace the three game feature to something more inline with the new theme. eg. stripe items, package and colorful bomb bonuses into something else. While it currently does have Facebook integration, I would like to expand on this and the user should (when reaching a new level) be able to share that on Facebook for a reward. I am looking for someone to work with long-term, and this should be taken into consideration. I currently have another 3 codes which I would like developed and re-skinned so please bear this in mind. I require someone to have excellent communication skills and who can read/write english very well. You should showcase some examples of previous work (if any) and you should be free to start soon.
