Iphone App Interface Design (No Coding)

We are looking for someone will experience of designing mobile apps for iphone and android to design the user interface for a new app we are developing. This project is just for the design work - NO coding is required at all. The app will be used to search for a local business in a particular category, and is based on one of our websites - so much of the design will be based on the website. There will need to be 4 pages designed: 1) Search Page - the user will have the option of using their current location via GPS, or can manually enter their zip code into a search box. 2) Company Page - this will show the name and address of their local company, along with customer rating (out of 5 stars), a button to navigate to a contact form, a button to navigate to a testimonials page, and a call back request form (name, phone number & email). 3) Contact Page - this will include a basic contact form and a send button. 4) Testimonials Page - this page will list testimonials and star ratings that the company has received from clients. We are looking for somebody that can complete this simple task within the next couple of days. You must have experience of designing apps, to ensure that the design of the app will function well once coded. When bidding, please give an accurate timescale to complete the project, and provide examples of other apps you have designed. NOTE: Just to confirm, we only require the design of the app NOT any coding work.
