Florida flats fishing help

I recently relocated to Miami and am interested in flats fishing. I was
wondering if anyone could give me any information as to what mile markers
might be a good place to stop and go flats fishing on foot (wading in). I
would like to try it this way before I invest an a flats boats. Come to
think of it does anyone have any suggestion as to modified v-hull that would
work on the flats as well as the open ocean say for loke dolphin that would
be around a twenty three footer. Also any ideas on baits for the flats,
artificials, dead, or live.

Thanks
