User Interface Design needed for a game app for the iOS

Hello, I'm going to try keep this as short and simple as I possibly can. I am creating a game app for the Iphone/Ipad and am looking for proffesional, extremely talented, value for money type freelancers who can work with me on coming up with a new User Interface for the game. I already have a user interface but I want to create a new one so I can test see which one is better. I am willing to pay $300 (as I am on a tight budget) for the right person with the appropriate experience in creating beautiful User Interfaces. I will need approximately 10-12 different screens some small and some larger, but they will need to be all similar template wise. It is a fixed price and I am based in Australia but don't mind transferring the money as US dollars. I have some images of similar games that should give you some inspiration and direction on what I need done for my own game. I have also attached a couple of images of my characters so you can see the art style of my game. I DO NOT want copies of the other games UI. They are there just for your reference. I need something new, beautiful, easy to use and original. My game: My game is about raising, feeding, breeding, collecting and evolving different types of Phoenixs in your own realm/Tree top. You place them on special habitats such as Fire, Cold, Air, Earth, Water etc. Phoenixs range from different breeds and types ie. Cold, Fire, Earth etc. My game is similar to games like Dragonvale, Dragon City, Tiny Monsters etc. Game screens of these games are attached for you reference. I also suggest you see gameplay videos of the games to get a better understanding on the game. Just search through Youtube. The images you create need to be phoenix related in some way. You have to be trustworthy, efficient, reliable, have excellent English communication skills (reading and writing). I am also looking for the person to have previous experience working with independent or large scale developers in the App Store business, on Apple. If you have the relevant experience and enthusiasm to assist me on this work then please feel free to respond to this ad. I'm friendly, I won't bite :) I like to talk through Skype and email as this is the best way of communication for me and people I work with on a freelance basis. You will need to provide me with a general sketch mock up of your proposed ideas for the user interface you propose. Relevant past experience is required so I can see your previous work. More work in future can be provided for the right person with the appropriate skill, experience and graphic design technique. Serious people only. Freelancer Graphic Designers with lack of experience won't unfortunately be considered for the task. Thank you for your time in reading this, I look forward to hearing from you. Peter
