DIY Kayak Loading Device for Hitch?

I'm trying to build a cheap gizmo to help me load my kayak onto the roof of my Honda Pilot (bad shoulder). There are the rollers that attach to your rear window, and with my wife helping that works well, but without her to help stabilize getting the kayak onto the roller I worry when I'm on my own I'll miss the roller and break my window.

I'd like to have something that attaches to my hitch receiver and sticks out a couple of feet, and has a vertical plug/receiver that'll take a 4 foot tall (or so) 'T' that I can put rollers on.

Then I'd have a lot less height to initially lift my kayak up and can then slide it safely onto my roof cross bars.

Anyone know where I can source those two things (plugs into my Honda's hitch and has a receptacle for a 'T' to plug into)?
