Which is the best flying school in the U.S. as per DGCA standards for Indian students?

My dream is to be a Commercial Pilot. Confused about the various U.S schools and related querries. Had shortlisted Epic Flight Academy, Florida but seems too expensive and quite over-crowded. Wud it be worth the price? How about RAA, Voyageur, Orlando Flight Academy, Ariben? Which of these would be the best bet in terms of training, fleet & the fee structure? Is it advisable to attend ground school cles prior to enrolling in a flight school? Which are the best ground school cles conducted in India to prepare for the DGCA conversion exams after obtaining a FAA licence? In the present fuel scenario, is flying a good career choice? How good are job prospects? Would really appreciate and be grateful for interaction with pilots who have been in my shoes sometime and istance & advice would go a very long way in helping me live my dream, for which help I shall eternally be grateful. Help me please...
