Need an APP for our outside service team

We are looking for an experienced developer to create a high-quality application for our outside service team. The app must be able to run on both iOS and Android devices, and it will need to provide stop-by-stop customer details with fields to populate with inv levels. We do not have an estimated budget for the app development, however we would like a bid that enables us to make an informed decision. With this, we are looking for a developer with a successful track record of developing high-quality applications. If you believe that you have what it takes to develop an app that meets our requirements, we would love to hear from you. Thanks for considering our project!
