I look for areas with moving water and bait when targeting flounder. I've caught them in 1' deep marsh drains on a outgoing tide and 20' deep channels on incoming tides. The point is look for areas with moving water where they can lay and ambush bait. Flounder don't roam around and search for bait like trout and reds, they like to lay up in areas where the current will bring the bait to them. Look for any transition areas from shallow to deep water that will have a good current flow during moving tides. It could be along the jetties, the edges of a deep channel, a cut in a back marsh, or even a culvert from a drainage ditch. When it comes to baits for flounder it really doesn't matter what you use, mullet, shrimp, jigs, spoons, or a cigarette but on a hook, they will hit anything you put in front of their face when their hungry. The important part is finding them. If your flounder fishing in a area that doesn't have any flounder than you will strike out every time. I prefer to use soft plastics over live bait for flounder for the simple fact that I can cover more water with it. Once you find a area that you think is holding flounder you have to make sure you cover every inch of it. Weather from a boat or the bank, when I get to a flounder spot I will cast out at 12 o'clock, then 11, then1, then 10, 2 then, until I cover everything, than I will move over about 10' and do it all over again. By doing this I cover every bit of the bottom. Only after I have covered everything with out a bite will I move to my next location. Some spots will only hold 1 or 2 fish, while others will have them stacked one on top of another. The only other advice I can give you is don't waste your time changing out different lures every 5 minutes just because you haven't had a hit. Get something like a red and white chicken boy on a 3/8oz jig head and cover it in procure and go to town.
