http://www.pacergroup.net/ , they do have everything you would need.
Also here's a pic of my mess. I used the fasteners from the cushion on the front of my console to thrubolt a piece of starboard to mount everything. Its hard to fit everything in a little boat (mine's a 18). Also I have my shelf set up so its easy to remove and I can squeeze into my console for adding stuff etc.I actually sit in there indian style, and I'm not a little guy!
Also I have my batteries side by side directly under the picture, which allows room in the front under the seat for lifejackets and stuff.
