Design an App Mockup

I am looking for someone to design an app mockup and logo. The app will be for an employee portal for an HR/Payroll software. More details and a very rough sketch/mockup will be provided to the selected candidate. Please see below the link to U.I's that I like. I am looking for something modern, creative, and original. There will be a total 10 pages to create. The user must be able to use invision prototype to present the work to me. This will allow me to see the mockup in a more interactive way. Ultimately I need someone with excellent design U.I and UX design. I will need the app to be coded to and I will also need a homepage to be redesigned. For now I want the bidder to only focus on delivering an attractive U.I, however, if the same bidder possesses the necessary skills to develop an iOs app I will naturally go with the same person (assuming the initial mockup was well done and presented) *TO AVOID CONFUSION. THIS PROJECT IS SOLELY FOR THE APP MOCKUP. THE OTHER THINGS THAT I HAVE MENTIONED (iOs App coding and homepage) will be separate project. My payment terms are as follows: Once a price is agreed upon I will upload the funds as a milestone payment. Once the work has been completed, the funds will be released. Well designed user interfaces [login to view URL] [login to view URL] These are just some projects that I like, this is not intended to be a template.
