Rod holder question

[Hoytman86]

I'm going to be setting up a new boat for trolling big boards over the winter and I'm trying to plan ahead some. Does anyone know where I can get some 6 rod trolling holders or someone that makes them? I'm going to have to modify them for the boat, but that's something that I can take care of myself. Just trying to save some time on the fabrication of the holders themselves since duck hunting is going to be consuming most of my free time for the next month. I'm also interested in an estimate to get an idea of what I'll be spending. I have some ideas for fabricating something myself, but if it's not going to run a lot higher to save myself time that would be preferable.

Any hello would be appreciated. Merry Christmas to everyone!
