How would I go about getting non-hobbyist fish for a 200,000 gallon aquarium I am building?

I've helped build a 200,000 gallon freshwater aquarium.To stock it I traveled around with my dad to help retrieve the fish straight out of their homes. We are attempting to build a 200,000 gallon saltwater reef aquarium for a different business. We have never done this. They are asking for many endangered species and exotic non-hobbyist species that without a city council approved permit, are illegal to have. The catch is, (no pun intended), we've got permission from the city, but we can not locate these creatures. This is because although some are fish, there are some other creatures. such as: Manatee, Thresher Shark, Sea Crocodile, Dwarf Manta Ray etc....The price of the whole project (not including the animals) is around 1.2-1.6mil. The business we are building it for is new, they've gained sponsors and grants for opening up their business, and this could really be the chance for my dad and I and the rest of the crew. We've thought about calling or getting in contact with Native Locals to retrieve them but not many have the equipment to capturing these creatures without harming it. I'm trying not to use locals though because even if they happened to capture the animals, UPS special services over-sea rates are HIGH; the Georgia Aquarium could have bought a palace with the money they paid a for their Beluga Whales and Whale Sharks, but then again the UPS Air Committee granted them $250k off of the move.Back to the point thought; Can anyone help? Btw, I'm a 15 year old marine aspiring marine biologist and entrepreneur. My dad put me in charge of researching plans for projects, while he and the crew follows through with them. Now obviously my age require parental consent but he is preparing me to run the business when he retires. I can't let him down; can anyone help?
