as you said: I had checked this pdf to estimate hov long it will take me to proceed
all the book. Those scans are little better than previous, but OCR gives
lot of errors to correct (because of many different fonts used
especially in numbers). All the book has 427 pages (minus few
informational gives about 420 pages of text. For the previous job I
calculated 30c per page and it wouldt give 126$.
I will do OCR corrections for 115$ (it will be about 27c per page) and
html pages for 130$.
