Phoenix FreeFlight

I have over 30 years in engineering office environment. Currently own DJI Phantom 2 Vision Plus and very happy with it.
Four years ago I was stricken with a disability that I can not continue with previous work environments and had to quit work. My insurance cancelled on me, I have lost all my savings and went thru foreclosure in 2018. I am trying to recover by trying to enter the commercial pilot environment and work closely with Goverment of Canada Watership Protection Program with drone being used for both identification and location collection needs of info which also includes underwater 3D Scanning and Charting of existing to post installation of lakeside ownership shore installations.
I know the Phantom 4 Pro would do an excellent job in this project. I am tempted to just add 5 axis sensors and upgrade main camera and also add additional cameras for multiscreen vision.
Anyhow I think this would be a project I could make some additional money at my own pace and would allow me that little bit more of normal lifestyle.
