Modify it to accept 0 to 1.999 volt by using suitable multiplier. Convert current into mV by using a suitable conditioning resistance to measure D.C. current. For 0 - 1.999Amp as 0 - 1.999 volt 1 ohm 5 watt conditioning resistance. if you feel this drop is high use 0 - 199.9mV range with 0.1 ohm 1watt resistance and suitably shifting the decimal point.

Go through the site indicated by Patrick Vaz down load PCB design and order with a PCB maker. Hi Rohit Kumar you can try with Vega Kits Mumbai.
