Recommendation for developers company

I’m looking for recommended developers company to develop a system to control large amount of rotors, each rotor with its own ESC using mission plan.
Thank you,

Why not do it yourself? it is documented: Copter Motors Library — Dev documentation in C++
or in LUA(does not even need to recompile the code, nor upload firmware) :

Here is a LUA example for an hexacopter:

It is easily expandable to up-to 16 rotors.
