Modify Plumbing Plans in AutoCAD

I'm looking for a professional to help me revise existing plumbing lines in my AutoCAD files based on the current plumbing plans I have in PDF. Please note that I have the AutoCAD files, so you won't be working solely from the PDFs.

Ideal Skills:
- Proficient in AutoCAD
- Experienced in plumbing design
- Detail-oriented for precise revisions

The project doesn't require adherence to any specific standards or codes, so creativity and technical expertise are key.
