Expert in Optical Character Recognition needed to improve app functionality

I am looking for somebody with outstanding Optical Character Recognition skills to help develop an iOS application. The application converts prices from one currency into another using OCR from the user's camera. A number of updates are needed, including: - Improved OCR capabilities - allowing the app to recognise smaller numbers and also allowing the user to highlight the areas of the image they want to focus on. - Recognition of numbers of various colours on various backgrounds - Offline functionality - A manual currency input option - Addition of Bitcoin and Ethereum APIs. I can provide more information privately after you have made a bid. Along with your reply, please start your message with the answer to 2+2 so that I know you have read the whole of this post. Thanks
