LED Bulb Driver Circuit Board Design

I want to start manufacturing business of LED bulbs. So I need PCB design for 4,5,6,7,8,9,10,11,12,19 Watt bulb. The circuit must contain LED driver IC with integrated Power MOSFET. The same needs to be tested at your end and after successful testing you will handover the design to me with all documents like BOM, Schematic, PCB gerber file and your calculations for components selection. Design the circuit in a such way that I can offer 5 years warranty on the same but with a compatible price. Also you should provide me technical supports and other testings support to obtain required license from the government for the next 10 years.
