When I used to beach launch my trailer boat, getting in was a case of hauling myself over the side, in waders, from waist high water. Not elegant but quicker and less faff than wading around to the stern (which was in the deepest water due to stern launching), then fiddling with the boarding ladder whilst attempting to manhandle the boat in the tide run.
No easy options for you I'm afraid, other than as others have already said to launch at a slip with a pontoon alongside or consider a marina.
