RFP for the Engine Build for the Missile

First of all thanks for all of the responses.
Over the past few years I have been told by others on this site that the simulation program I am using is fairly accurate, so I am confused by all the comments that the build I outlined wont do what the program says it will. That being said I put this thread together to solicit package specs that meet my general needs based on what you can see of my unprofessional design work. Also to get a cost on having that package built.
The use of a dual plane was because of the proven low end torque they produce, where as a single plane is for top end power.
As far as the power band goes , what about lobe separation? where does that come in?
I am still interested in discussing this let me know
