I have a meeting with a newspaper to discuss working on an android app for a non-profit event that is held at my university (I'm a graduate) every year. They have an iphone app and are looking to have an android app made too. My friend who works on a committee brought my name up when they were asking about the app.
I'm very capable with Android. I work as a software engineer, though not on android stuff, but my problem is I only have 1 fully functional android app that I feel is good enough to show off.
I've never worked a freelance job before and I was wondering what the protocol is when meeting with potential clients. I'll obviously bring my resume, but should I expect to demo my app? Is 1 app enough? I have other stuff that I've written, but it was mostly for educational purposes, so I stopped making it look good after I learned how to do whatever it is that the point of the app was.
tl;dr: What do freelance app designers usually show off during meetings with potential clients?
