To make things more difficult, some of the text are in columns :/

The software Markom mentioned,
k2pdfopt (open source, available for Mac), uses the Tesseract OCR engine if you turn on OCR. That does a pretty good job if the text is well defined, but it is slow--you may have to run the conversion overnight. It should be okay with multiple columns, depending on the complexity of the layout. You can try things out on a few pages at a time. For an example of running the text menu version (like on the Mac) and turning on OCR, watch the 6-minute video on
this help page.
I have read on these forums that the best OCR is done with ABBY FineReader, which is a commercial program.
