Damn i must come to the rescue of everyone.....lol. Here is a site i use for all of my automation needs, damn good prices to. I will try and get a video of my tailight actuator i have.

Here is a listing of 150-200lbs actuators, which i would think would be more that enough for your application. I think they sell controllers too, i just make my own.
