Mobile Application Development (Android and iOS)

I want to develop a mobile application for a real estate company. There is currently a mobile app I use that mimic's exactly what I want my own to do but in a different field. I would like to do a 1 hour a consultation where we can go through the existing app and choose the options that are relevant to my business and then get a quote for the design and build of the app. I will pay $100 USD for the consultation payable upon receipt of the quote.
