There seem to be 5 types of PDF files.
PDF (Normal):
The PDF file can be viewed and searched in a PDF viewer and edited in a PDF
editor.

PDF Edited:
The PDF file can be viewed, searched and edited.

PDF with image on text:
The PDF file is viewable only and cannot be modified in a PDF editor. The
original images are exported, but there is a linked text file behind each
image, so the text can be searched.

PDF with image substitutes:
As for PDF (Normal), but word containing reject and suspect characters have
image overlays, so these uncertain words display as they were in the
original document. The PDF file can be viewed, searched and edited.

PDF, image only:
The original images are exported. The PDF file is viewable only and cannot
be modified in a PDF editor and text cannot be searched.

Since you already have PDFs, you may be only able to change the current
configuration with the only software the can edit PDFs, Adobe Acrobat family
of products. Acrobat Professional is the top of the line, Acrobat Standard
has fewer features.

There are several other software that can create PDFs, but not many that can
edit a PDF after it is created.

I do not think that there is a low cost solution to editing PDF.
