Transform Scanned PDF into Editable Text

I have a scanned PDF that I need to be edited and made into an editable text document. The required editing will involve substantial changes such as rephrasing and adding text.

Ideal Skills:
- Proficient in PDF editing software
- Excellent typing and proofreading skills
- Strong command of English language for rephrasing and editing
- Attention to detail to ensure accuracy in the editing process
- Experience with substantial text modifications

Please note, I do not have the original document, only this scanned PDF.
