Working as a Senior Software Engineer for a reputed NASDAQ BPO company, Which involving software related with PDF, OCR technology, I have vast experience in PDF conversions (any PDF other than hand written). Image PDF, Searchable or Scanned PDF can be converted very accurately, If pdf quality is good, I can give u text accuracy 99.95 or more.
Advance OCR technologies (fine reader 12) and integrated proofing and markup tools will make this a success. If interested I can convert sample for you.
Thanks
