Long shot, but perhaps someone does this stuff here. We are looking at a place in Florida that has a dock which is about 100-150 feet from last channel marker. Water is deep in the channel (about 6-8 feet) but from the last marker to the dock itself depth drops to 1-2 feet making the dock unusable. I understand that there are companies that specialise in dredging channels and all that. Assuming the bottom is soft, what can one expect the cost of dredging 100-150 feet channel to the dock may be? I am guessing there is no way to do it yourself.
