If all of the PDFs are simple like your example, it may work okay using AutoCAD.
But, I would concentrate on fixing the text in the PDF before importing to AutoCAD. Maybe check some Adobe Acrobat fora and/or research the pdftoedit, ImageMagick, Ghostscript, etc.
Overall, if you have a lot of them to do, you might be happier with the results.
On that note, I have seen PDFIMPORT scripts, LISPs, etc. So fix the text in PDF, then batch create the .dwg for them.
