[Qgis-user] Assistance with high-level use case of QGIS for commercial use

[Dave Tobias]

Many thanks to James, Brent, Alexander and Andreas for the suggestions.  It
looks like PostGIS offers the best option for the limited complexity of the
solution.  PostGIS is not something I had worked with before or considered.
After doing a bit of research and referencing the code/process Brent
offered, I think we have our path forward.
Thanks again!
Dave
