HI I'm Victor Pinto from Peru. I'm a C# programmer. I worked with Unity3D and Vuforia SDK since 2012. I know very well Vuforia features. In my previous developments I've used ImageTargets, which is you´re looking for, VideoPlayback, CloudRecognition, UsedDefineTargets, VirtualButtons, Framemakers and other extern pluggins like screenshot capturer, social sharing, QR Scanner,etc. And about Unity3D I worked with animations using Mecamin, a powerfull feature of Unity. I could make simple animations like translate, scale or rotate objects. And finally building this Unity project for Android and iOS. Don't afraid to talk me for more details. Greetings!
PD: Referencial price. I need to capture your requirements in order to make a more accurate budget.
