Wanted App Designer

We are seeking an App Designer, who can provide us with some graphical explanation screens for a Product Rental application - For example, initial tour pages that explain how the app works, purchase success pages, etc We already have the Wireframes for an app that I am having developed. The app is a way for Consumers to list their products that they want to rent out. I have a rough prototype drawn up using keynote Figma the designer can reference. I'm looking for someone who can offer their input on how to create a better user experience and design. My goal for the application is to be easy intuitive and clean. I will need someone who can communicate via phone or video chat to clearly communicate all the details of the application We would like to see the following: - A mock-up of what our mobile app could look like with a redesigned interface with the current color scheme - A mock-up of what our mobile app could look like with a redesigned interface with a "light" color scheme - A mock-up of what our desktop app could look like with a redesigned interface with the current color scheme - A mock-up of what our desktop app could look like with a redesigned interface with a "light" color scheme I will share the Designs after I chose the designer and sign the NDA. Thanks.
