Two rotating discs, synced and remote controlled. Answered

I realized that I change the angle of my speakers many times a day and it gets really cumbersome. To use my time better, I thought that I'd be nice to have motorized rotating discs under each speaker, wired so that I could adjust their angle from a simple remote controller on my desktop. This would be because if there's a program, the speaker angles would always remain in sync in relation to one another, and because sometimes the speakers are actually located a bit inconveniently in terms of getting near them to adjust the angle manually. 

Take a look at the attached image. I can't get that stupid image uploader to work, it uploads but doesn't keep the file, so here goes:

Before you start criticizing it, don't: The point of the image is to demonstrate a principle. It doesn't tell anything about the room that the furniture is in. It isn't in scale. The sound fields of the speakers aren't trying to portray reality accurately, they're just there to make a point. Everything in the image is a rough sketch and its purpose is to make explaining easier. 

As you see, the situation is that sometimes I sit at the desk, sometimes at the back of the room. If I keep the speakers pointing almost straight (like image 2) while sitting at the desk, I feel like most of the sound really "opens up" behind my back only, going past me. If I keep the speakers in 45-degree angle (image 1) but decide to watch videos from the sofa, again I feel like the sound isn't quite pointed at me and it's especially difficult to listen to dialogue.
Before you start talking about the room - yes, I know about acoustic treatment and I'm taking it onto account already, but my auditory processing isn't normal so the acoustic treatment alone isn't enough, speaker angles make a huge difference for me. I'm saying this because the internet is full of people who get too caught up on the actual principle and start explaining why they think that I don't need something or don't have a problem with something. From having manually adjusted the angle thus far, I already have the experience of how this makes my life easier.

I'm looking for advice/help or someone to make this for me as a service. Due to shipping costs, makers should be in Europe only. Advisors who could guide me through, doesn't matter where you are.

I'm guessing that besides the disc parts, the remote control would require knowledge on electronics and coding of microcontrollers. The controller could either have a wheel or simply two buttons, one closing the speaker angle, other spreading it wider. The angle range only needs to change within 90 degrees so that suffices, but the program doesn't need a specific angle limiter made if it happens to be able to turn, say, 360 degrees.

Taking ideas of methods, estimates, part choices and possible compensation fees!

I would say all you need is two servo motors as used for RC models and a little Arduino.
As long as you want the same angle for both speakers you can use the same code for both servos, just let one run in reverse.
Attached to a little "Lazy Susan" or other rotating platform your speakers will always point in the set direction.
If you want to go totally crazy you can even use sensors to check where the listener is and adjust the servos accordingly.
Examples for servo control are available in the Arduino library and many examples can be found on the web.
