Are you THE BEST with Sounding Rockets?

Have you studied astronautics and/or astrophysics? Do you know all about how sounding rockets work? Are you able to look at new concepts for rocket engines and almost instantly decipher if they will work or not and what their pros and cons will be? If so, then please read on! I am an entrepreneur who was born and raised in New Zealand. I am looking to embark on my own private space program, which will start with sending a simple, sounding rocket to the edge of space (at about 100km in altitude) with a small payload of just a camera and end with manned missions into space. Currently, the main focus is this first sounding rocket project, which needs to be constructed in and launched from NZ - for NZ $100,000 or less. I am already in touch with the NZ Rocketry Association to ensure that my rockets meet the new High Altitude Vehicle (HAV) laws in my country and to have a place to launch the rockets from. I have also looked into Rocket Lab (NZ) and have spoken to the Centre for Space Science Technology (CSST) in my country. What I now require is an individual who is gifted in aeronautical engineering (and related subjects) to look at a concept that I have come up with for a new rocket, which is a hybrid of a conventional rocket and hydrogen balloon. I am aware that this has been proposed since the 1960s and that there are currently private firms looking into it such as Xero2infinity with their "Bloostar" concept. However, my concept is a tad different and I now need a professional to assess it and see if it will actually work, is feasible and what sort of payload it could carry into space. The assessment will need to be accompanied with calculations so they can be depended on by my team in NZ. In addition, these calculations MUST have some form of verification or testing done on them with a computer program so I know that they are, virtually, 100% correct. I am happy to sign a non-disclosure agreement throughout this project to protect intellectual property. PLEASE ONLY BID IF YOU CAN DEFINITELY DO EVERYTHING I AM ASKING FOR. THANK YOU.
