Try Conklin and Decker , they produce a very detailed, comprehensive program that does exactly what your’e looking for. Of course you should also get an experienced consultant to advise you with regards to the numerous other requirements, regulations ect…
At least this will help narrow down the aircraft choice for your specific mission requirement.
Good luck.
