Hello,
I think that i can help you with this application design, i have made four mobile application designs till now tow of them is small and two are considerably big, and also made some template designs for learning the basics. To be honest i'm new to mobile design but i have good experience as a designer for media companies. You will see my portfolio considerably empty because of some photo size problems at the website but i can send you sample if you would like to. also to be honest i put the lowest bid because i'm looking to build my career as a freelancer and make good feedback.
hope to be useful for you ,
Thank you.
