I need a marketing specialist

I have invented a device called the Fuel Economiser. When retrofitted to existing space heating systems, it has reduced energy usage, consumer fuel bills and CO2 emissions by in excess of 50%! Twenty million homes in the UK qualify for this. I have ben awarded patents in the UK and the USA. I have engaged a Company that can produce the Fuel Economiser in quantity in pcb format. I now need help in marketing.
