Exiftool help

I am looking for someone to help me with a particular task related to Exiftool. Specifically, I am looking for someone who can help me edit metadata. It's important to me to find someone with the right level of familiarity with Exiftool, as I'm a beginner; however, it would also be great to have someone who could provide some tutorial-style assistance with the program in the future, just in case. Thanks in advance for your help!
