fitness women over 50

How much profit will I earn in Fashion/Fitness Magazine?
Hey there Everyone! I am a Sophomore in College and I would like to publish a magazine about fitness and fashion for women from 18-50 years old. But before I start, I would like to know how much profit will I get out of it? I am not thinking of a Elle or Vogue type of big magazines, but a smaller one that targets only one state. So Please advice on whether it is profitable business or not!
