Beast2 XML Integration

I'm seeking an expert in Beast2 v 2.7.7. My xml file is running already and providing the log and Bayesian tree, but I need help with the last small step: getting the Bayesian tree output to display historic dates based on my linguistic data.

Requirements:
- Experience with Beast2 software
- Ability to work with xml files
- Familiarity with Bayesian tree outputs

Please provide an overall project cost, not hourly rates.
