Inverter Design

I am looking for an experienced engineer to design an inverter for me. The power capacity of the inverter must fall in the range of 1kW-5kW, and I need it to be a bi-directional model. No user control or display is required for this project. The successful freelancer will have to demonstrate expertise in electrical engineering and inverter design. The inverter must be designed within agreed timelines at an acceptable cost. If you think you have the skills and experience necessary for this job, please apply for the project. There will be 6 signals coming from a MCU so those 6 pwm signals will be switching the MoSFETs. The current can go upto 400A and voltage to 120v. The system works on a 72v system from a Li ion battery. I need the inverters designed for 6 mosfets in a three phase half bridge configuration. Each mosfet is paralleled in 3 so total of 18 mosfets are present. The MoSFET used are IRFP4568
