Provide a smartphone charger circuit diagrams for the required features

I want to have circuit diagrams for mobile phone charger for which various technical specifications have been listed below and all specified smart phone chargers must have features like Over voltage protection, short-circuit protection, over charge protection, high temperature protection etc. Also it should have fast charging technology something like smart Q which smartly detects devices connected, choose suitable current to charge at fastest speed possible. Adding further It should automatically stop charging the device once it is fully charged. Tech specifications for various circuit diagrams: • Input 110-280v 50Hz AC, output single USB port 5v dc @ 3A, just like Qualcomm certified quick charge(TM) 3.0 port which should provide 4 times faster charging than regular chargers • Input 110-280v 50Hz AC, output 5v dc@ ~4amp with 2 usb ports, 1) 5v@ 2amp, 2) 5v@ 2amp. • Input 110-280v 50Hz AC, output 5v dc@ ~3amp with 2 usb ports, 1) 5v@ 2amp, 2) 5v@ 1amp. • Input 110-280v 50Hz AC, output 5v dc@ ~5amp with 3 usb ports, 1) 5v@ 2amp, 2) 5v@ 2amp, 3) 5v@ 1amp • Input 110-280v 50Hz AC, output 5v dc@ ~7amp with 4 usb ports, 1) 5v@ 2amp, 2) 5v@ 2amp, 3) 5v@ 2amp, 4) 5v@ 1amp • Input 110-280v 50Hz AC, output single USB port 5v dc @ 2A for any smart phone or similar device So finally I need total six various circuit diagrams for six various technical specifications as mentioned above with all standard aforesaid features (like over voltage protection, over charging protection etc etc..) mentioned in the beginning itself . Choose standard quality components and all the selected circuit components should be easily available in Indian market and final circuit should have been successfully prototype tested and should good to go for pcb designing & manufacturing. Also need a technical documentation containing detailed explanation of the working of the circuit which also should comprise how each and every component along with its value contributes to the successful working of the circuit tested and how you have chosen the value of each and every component so need that calculation as well in the report. Kindly reply if you are pretty sure that you can accurately develop the circuits which fulfill all the requirements mentioned above. At the outset, I want to make my final product as cheap as possible without compromising the quality of my product. Note: My final circuit should smartly support fast charging to all android, iphone smart phones, tablets and other similar devices.
