I want a guy who is very experienced in geochemical modeling on PHREEQC

I'm looking for an experienced freelancer to help me with geochemical modeling on PHREEQC. I need help with reactive transport modeling, specifically. I don't have a specific project or dataset that the modeling will be based on, but I do know what I want to learn about the software. I have a beginner's level of experience with PHREEQC, so I'm looking for someone who can help guide me through this modeling process and provide the hands-on guidance I need to learn the software. The ideal freelancer will be knowledgeable in PHREEQC and reactive transport modeling, so that I can come away from this project with a comprehensive understanding of what I'm learning.
