Check out PDFMASHER,
Here is a link to a posting about it here:

Ive down loaded and used it a couple of times, its VERY nice. Nice enough that I donated to the author to help support it.
It will read in a PDF file and allow you to sort the text several ways, you can mark sections to be ignored when it generates its output.
It will create a HTML file you can then edit and clean up, altho I have found that this program doesnt require a lot of cleaning up after.
What I would do is load the pdf, and then scroll down, each section tells you what page / line the text is related to in the pdf.
I would then just high light the text for every other page (easy to do with this program ), mark it to be ignored, generate the output and then edit the output file to your hearts content.
