Pix4Dmapper Expert Needed for Urgent Data Processing

I'm looking for a seasoned expert in Pix4Dmapper to help process a challenging dataset from my DJI Mavic 3E. The project involves a lengthy 24+7 km corridor and a vast 3,200-hectare area, both of which are densely vegetated and have limited ground control points (GCPs).

Key Details:
- Flight Altitude: 135m Above Ground Level (AGL)
- Overlap: 60-70% side, 70-80% front
- Images: Approximately 7,315
- Required Deliverables: Orthomosaic, Digital Elevation Model (DEM), DXF contours, and a Google Earth KML

Current Issues:
- Camera calibration errors with over 15% difference.
- Distorted contours with errors exceeding 5m.
- Outputs are heavily inaccurate.

Requirements:
- Extensive experience with Pix4Dmapper and processing drone data in vegetated areas.
- Proven ability to optimize camera calibration and rectify data distortions.
- Quick turnaround time is crucial.

The primary focus of this project is achieving the highest accuracy for the DXF contours, as these will be used for construction planning. The overall accuracy of the outputs has been a significant concern thus far.

Please note that I will upload the dataset to WeTransfer and share the link with you upon hiring. I would appreciate if you could provide your proposed price and timeline for this project.
