App Design, my favorite type of projects.
Hello, my name is Omar.. I'm a Graphic Designer, so I'm bidding on the UI/UX (User Interface/User Experience) Design side of the app. I'm not a developer (programmer).
I read your project description and I find this to be an interesting idea, which I will be happy to help make it come to life.
I believe design will cost you far less than 750$ (I can't bid for lower than the budget specified here) since from the description, the app doesn't have much screens to be designed. I will give you accurate pricing once we talk about it, I will draw you some mockups to define the scenario of the app (UX) and once we agree, I will start working on the interface.
I believe the design phase won't take more than a week, it's a small app.
Also, I will remain on project with the developer because there will always be things he wants from the designer etc. So I'll keep working with the developer until the App is up and running.
That's all for now, do not hesitate to contact me anytime if you're interested. And feel free of course to have a look on my profile, you'll find a few samples of my work there, just to give you an idea about me.
Have a great day :)
