Hello, I'd be happy to help you in any way I can with this project. I am an Objective C developer. I have experience with making Objective-C based iPhone apps, and some experience with Mobile Substrate tweaks. The patch shouldn't be a problem, and as I learn more about Mobile Substrate I can definitely help you with future projects. I'm based here in the US like you, and I'm fluent in English(unlike many other freelancers on this site). I have 2 Apple computers both running the latest OS and XCode, along with a jailbroken iPhone 5C running iOS 8. Feel free to message me if you have any questions and we can get started. I'm trying to get some first positive reviews on this site so I greatly appreciate your consideration. Thanks!
