Need a freelancer for installing two hub motors to lithium battery

We need help with an upgrade.
Currently we have
One lithium battery, and one hub motor with BMS
We are adding two more hub motors, each one has its own controller.
Everything is 48v.
We need someone to help wire the controllers to the Battery/BMS properly.
This person should have a lot of experience and know how to completely configure BMS controllers and hub motor controllers.
If things work out well, we will have more work for you. Eventually we will have autonomous electric vehicles.
We think we need you for one day's work. The actual work will probably be completed in 2-4 hours, but there could always be problems.
You must be friendly and welcome our questions about the technology. Our company builds electric vehicles, but in Israel, we don't have a lithium battery technician. We have us, and we do marketing and design. We need some help.
