Design Wireframe and Graphic Prototype for our Mobile App - open to bidding

This is a business app that will include a e-commerce store, admin panel, and more for android and ios. I need a UI/UX designer to design a wireframe (blueprint or sketch) to show what, where and how things will work within our app (see example 1 and 2). This will give a development team a clear and understandable wireframe design plan. This will probably consist of 50+ wireframe screens , then after that, those screens converted into a graphic prototype (see examples 3 through 7). I will need someone with a clear understanding and experience in mobile app design as we will need help with the implementation of screens and features that we may be missing in our plan. We want this to be as user friendly as possible so experience will definitely be needed. I do not pay in advance for work or pay for incomplete work, I only pay when the project is complete, we can talk about paying half when wireframe is complete, then half when prototype is complete. No payment will be made unless a completed version of wireframe and/or prototype is made and to my satisfaction. Unlimited revisions until satisfaction is a must. I give you more information if you are agree to my terms and if I have quotes and turnaround times, feel free to include that in your proposal, or message me for turnaround times.
