TOUGH2 Reservoir / Hydrogeology / Geothermal Simulation: Convert 2D to 3D & Flow Rate Matching

I have a project based on TOUGH2 reservoir/hydrogeology simulation software. The task is almost completed, and only the final step remains:
• The grid has already been processed, and I have a finished 2D case with plots.
• I need to convert the 2D model into 3D.
• Adjust the flow rate matching so that the 3D simulation results align with the previous 2D plots.
• The working conditions remain basically the same; this is mainly a dimensional conversion and flow rate adjustment task.

Deliverables:
• Corrected 3D TOUGH2 input file(s)
• Output results that match the previous 2D case plots

Please let me know:
1. How long you estimate this would take.
2. How much you would charge.

This task is suitable for people experienced in:
• Hydrogeology modeling / groundwater simulation
• Reservoir engineering / CO₂ storage / geothermal modeling
• Strong background with TOUGH2 / TOUGHREACT
