Looking for Firmware developer in TI and STM microcontroller for DC DC Converter & Inverter Projects- Any one project only can quote

Looking for Firmware developer in TI and STM microcontroller for DC DC Converter & Inverter Projects. I ve two power electronics products to be designed with reference to the Ref Design files. These are 1). DC-DC buck boost Converter and, 2). DC-AC Inverter design. I need to give one project to each freelancer. Both projects can not be given to single party. So, each freelancer needs to quote with mentioning the which project is interested. The scope of work includes Redesign schematic w.r.t ref design, components availability check, update the BOM list, PCB design, Firmware redevelop or customization, addition of communication, LCD display and protection scheme implementation. Once all design complete, them the source files need to handover to us. We need to make prototype, during testing of prototype the freelance needs to support us to finetune the product.
