Electrical schematics and PLC design for chemical reactor skid

We are developing a small-scale ammonia reactor demonstration system for a project we are working on for install at a research facility in Sydney, Australia.
The process skid is very similar in size and scope to an existing testing unit we have in the lab, which is controlled using a Siemens S7-1200 PLC. We've added some functionality compared to our existing set-up. so are looking for someone to help develop the electrical layout / schematic for the new process plant and advise on the installation requirements. We could also do with assistance programming the PLC.

We have a P&ID, asset list and specifications already, as well as the PLC code, electrical schematics and wiring diagrams for the current system. The I/O counts and type of equipment are broadly similar between the two plants, so there's quite a bit of cross-over. The system will also include a SICK safety controller.
