Looking for an old CCTV pan/tilt mount or antenna rotor for a project!

Elloooo...

I have an exhibition coming up very soon, and I'm trying to build a satellite tracking system.

For the mechanical side, I really need a pan/tilt mount, an old antenna rotor, or one of those old motorized CCTV mounts.

The problem is the deadline is getting super close. Building a custom mount from scratch is just going to cost too much time and money right now. My best bet is to find a salvaged or broken one that I can fix up and repurpose.If anyone have an old one lying around in a junk bin that you don't need anymore or anyone know a good place where I can find one of these quickly...

Any help, leads, or donated parts would be massively appreciated.
Thankuuu : )
