How do I check water yielding capacity of borewell - Please suggest correct hp motor for 600 feet deep borewell

I have a 6 inch borewell, 600 feet deep. The water availability is from 270 feet. Would like to install a motor. Please suggest an efficient solution to pump the water from bore well.

Plan to install motor with 450 feet depth either compressor or submersible one (not yet decided). I look for your valuable suggestion on deciding the motor. If I install the pipes for 450 feet, what will be the motor's horse power required? Please suggest a solution.

Would like to check the water yielding capacity in the bore well. How do I do it? More over, the complete bore is in the rock no sand in between. Expect your valuable recommendations and suggestion via email.

Thank you in advance.
