A postal service kinda like UPS.
- National or International Letter Delivery Service
- National or International Package Delivery Service
*packages could be divided into S/M/L package sizes
*additionally normal or priority mail
- Cardboard boxes, Envelopes , stamps
- Package Labels
- Duct tape?
- New Sorting machine
- New Large scale
- Pallet / Storage shelf
- Planes and boats ( larger scale?)
This business type would go great with my other suggestion but instead of a home delivery it would work as home collection.
