Need Android and/or iOS Developer(s) for Zapcode scanning app

Looking for an Android and/or iOS developer to make a Zapcode scanning app. The app will scan camera feeds in search for Zapcodes. Once detected, it uses unique identifiers to download content from Zapper server and display them on screen. There're Zappar SDK in aid for the development, and API calls to retrieve information from Zappar server. The app doesn't have to be fancy. Write a sentence of random characters at the end of your proposal to prove that you've read this description. Basically, it is a custom branded Zappar app [login to view URL] I don't have a fixed budget, just give me the best price and how long it will take you to make. Will you develop on either Android or iOS or both?. Also give me your portfolio so it make it easier for me to make decision. Thank you.
