Contractor for EtherCAT Master Redundancy?

We are a company to provide the vehicle crash testing equipment. We are looking for a contractor for the EtherACT Master Redundancy integration service.
Here is the background of my current situation. I have an EtherCAT master controller now together with some Beckhoff EtherCAT devices. We need run our crash test system in real-time. We bought Acontis EtherCAT Master feature package and made it work with our NI Linus RT controller. We also have NI Linux RT to run our Labivew software which is used to control our motor with the control algorithm. It is easy to do the algorithm and calculation in Labview. We had our own C program in NI Linux RT which calls the Acontis EtherCAT Master library to run EtherCAT Master and also we have our Labview program running in the NI Linux RT as well. It works.
But our customer put control system redundancy in the contract. They require if the RT controller has power failure during a test, the system can still continue and complete the test with the control system redundancy. I am looking for a solution to integrate the EtherCAT Master Redundancy feature into our own EtherCAT Master program.
I am looking for a contractor who is willing to help us integrate the EtherCAT Master Redundancy into our own EtherCAT master program. If you have interest, I can send you more info about our system and we can set up a meeting. Please let me know. Thank you.
