I am looking for a designer to take the existing UI of our Procurement Management System and create a new Responsive UI using Pinegrow. This will be a hourly job as it will most likely take many iterations to get a design that everyone likes. The project will consist of an initial collaboration call to go over our existing system and what we would like to accomplish. We would then like to see a conceptual look and feel design and review and modify it. This second step will most likely take several iterations to get everyone to agree. Once that is accomplished, we would then want the screens designed using Pinegrow. The back-end of our system will be redesigned as required to accommodate the UI changes. Please advise me of your rates.
