Need Proofreaders for Tamil

I am looking to hire proofreaders for checking errors in text extracted from scanned copies of books by OCR. Please provide your quote based on a page basis. I am having different books of different page sizes and fonts. So, I am unable to provide a word count at the moment. Some of the books may be in old Tamil font. I need 100% error free work without the need for someone to double check it. Thank you.
