mobile app for pet needs

I am looking for a freelancer to design and develop a mobile app for pet needs. The app should be available on the Android platform. I am open to suggestions regarding the design and layout of the app. The most important feature to me is location-based services - this will help pet owners find the services they need near them. I am open to any other features you think the app should have that would be useful for pet owners. Thanks for your time and assistance in this matter.
