Which motor, pump and pipe to use in a borewell?

Hi, I had dug a borewell inside my house in Bangalore, with the total depth of 900 ft. Water level is at 250 ft but there are four gaps in the borewell at 179 ft, 380 ft, 760 ft and 790 ft. Also, there is so much mud in the borewell. Please advise which motor, pump and pipe should be used.
