Data Entry from PDF to Excel

I have about 50,000 PDF files that most of them are scanned images. You will have to open each file and look for the information needed to fill in the spreadsheet. There are anywhere from 5 to 10 fields to be imputed on the spreadsheet. Not all PDF files will have all the fields, but some will. The spreadsheets have different tabs. Each tab is a state. And there for the data will have to be put in on the correct tab and or sheet. There is no major rush to get this done, but would like it done in a reasonable amount of time. I would like to be kept updated on the progress, and would like to see the progress being made. At the start i will have you do a few of them to make sure the right data is being collected and put into the spreadsheet.
