Welcome to the Wannabee forum! You will find lots of people here willing to help you get your foot on the first rung of the ladder. However they all have their own views of which school is best and even differing views of a particular school. They also expect that you will have done some research already.
May I suggest that you spend a little time using thew Search function and not only will you find a lot of articles about flight schools but also you will learn a lot about the aviation industry that you want to participate in.
Good hunting
