You can find graphic artists at very reasonable rates on elance.com (be sure to check their ratings) I would advise however that you also consider working with a UX designer who has experience with the design of navigation/workflows and who understands usability best practices. Having a well designed and usable (intuitive) product will make your product stand-out and will make users more likely to enjoy the experience and return for more. This is especially true when it comes to social apps. I would also advise that you make it easy and enticing for your users to leave feedback. This feedback will be the key to understanding and identifying their needs. Then you can consider how to best meet those needs (if possible with the help of a UX professional).
