Multiple servos Move random (semi urgent)

Hi, I am currently making an animatronic dragon, and I want to use my arduino 101 for servo control. I want to move two servos individually, at random intervals and distances. I have seen several codes that do pieces of what i want, like: Blink random, Blink multiple random, and servo control. I feel, as a new coder, that combining these is a bit over my head. Any help is appreciated, thanks! I also am on a small time budget, so aI would perfer a quick reply over a quality reply

How much are you paying for a quick reply?

Just get the servos sweeping back and forth coordinated together. That checks that all the wires are working and your power supply can handle the load.

Do the random stuff later.
