Boat slip/ dock /dry stack

Hey does anyone know of a slip, dock, or dry stack in the Mount Pleasant, sullivans Is, IOP, Daniel Is area. That 1. is available 2. can accommodate a 23ft boat w/out a TT. and 3rd is $200.00 or less a month. I know the last one is hard to find. Just missed a dry stack on DI for 250/mo.
I am also open to renting part of someone’s private dock. I am responsible and low key with a wife and two kids 9 and 11. Boat used mostly to take family out. I would like to improve my fishing skills but that has not happened yet.

Thanks
