Hi Kris,
As John mentioned, lamp cord should work for your application, and your idea of using speaker wire will work as well, Keep It Simple. I have been in the professional Audio/Visual industry for 30+ years and professional speaker cable is extremely flexible and the vinyl jacket is both tough and flexible. It gets CONSTANTLY wrapped (over/over which is the wrong way), yanked, kinked, pulled, dragged, ran over, etc. in all sorts of environs and I have never had any fail due to breakage. If you do decide to use speaker cable look for a jacket that is PVC as some contractor/install grade cable may be too stiff for your application since it is designed to be fished through walls so the jacket is usually much tougher but not all. Another advantage to choosing speaker cable is that you can get 4 conductor if that would be a benefit to you. One other tip is to stay away from aluminum clad wire as it has a much higher resistance. Generally OFC (oxygen-free copper) is basically all that is used in pro-grade speaker cable. Also, since speaker cable is designed for high-current applications 12-16 gauge should work for most applications.

You may also be able to find cable at Home Depot, OSH or Lowe's. If you have any in your are you can also check with local pro audio stores.
