Please suggest the right type of submersible pump in terms of make, power and capacity

I would like to know whether Crompton Greaves submersible pump or C.R.I submersible pump would be better for lifting water from a borewell of 4 inch dia, drilled upto a depth of 780 feet but  whole of the depth cannot be utilised because of pump and pipes falling down at the bottom and can not be recoverred from below by conventional means, water level is available at a depth of 120- 150  feet at present. what should be the specification for such submersible pump to lift water from say 350  --400 ft depth,  i mean the HP of the pump and the stages and the amke--- please earlier the better.THANKS
