Looking to Convert E-commerce Website into IOS App

Looking for a developer or a whole development company for my iOS app development in UAE. The app is an E-commerce project. It would include all required features like shopping cart, payment integration, etc. You can comment if you are experienced in developing such apps. I want something like Ingic. I hired them some years ago. They were so professional in their work. They paid attention towards my project requirement and helped me get the best out of m investment. Their project manager was so friendly and courteous. He managed everything so smoothly and kept me in the loop with even the minutest of revision.
