Experienced and creative UI/UX designer for a crypto-currency wallet webapp

Hi, thank you for your interest in this job post. We are a startup company developing a crypto-currency wallet webapp. We are currently looking for an experienced and creative UI/UX designer to add to our team of web developers. You will be designing the interface from scratch and creating the wireframe of the interface. We expect the work to take about 15-20 hours spanning over a week or so. We have a general idea of what the UI should look like but we are just starting with the webapp so we are looking for someone who is not afraid of voicing their own ideas. This project, in our opinion, is something very interesting and if we get things right we can make this into something big. If you are interested please submit your proposal with examples of your previous work. PS. Although this is a crypto-currency related project, we are not some ICO scammers. This webapp is part of a legitimate product and you will be paid in US Dollars.
