I'll offer a pessimistic response and a hopefully more helpful response.
Pessimistic: Other people with actual experience doing this have already told you it isn't feasible. Period. You simply won't get your waiver. I have been in HPR for 3 years and have my level 2 cert and just use commercial motors. That's as fast as I have been comfortable with progressing. Just reading other people's stories and hearing campfire tales about Black Rock, I can promise you, you have no business attempting something like this yet. Don't ask for money when you don't know what you are doing AND can't get approval for it anyway. Not to mention, where did the $10k figure come from? What is the cost breakdown? You will need pretty detailed documentation to get said waiver, and you probably don't even have enough of a fleshed out plan to explain what it will actually cost. Do you think one person with $10k built Qu8k? Lastly, do you think "Fortunately it flew well" would look good on a resume? "ELON, I DON'T REALLY KNOW WHAT I'M DOING BUT I FLEW A BIG ROCKET ONCE AND FORTUNATELY IT FLEW WELL. HIRE ME?!?!" Don't bother people asking for money until you have multiple projects that can be described as "It flew exactly how it was supposed to".
Helpful: Get money from a job, or from your parents, or from trading crypto, whatever. Buy some smaller HPR kits and start working on certs. You will learn so much from crashing those rockets on your own dime than you would from attempting a giant sugar rocket. Next (and this is something businesses spend tons of money on consultants to teach their employees), develop S.M.A.R.T. goals. Specific (100k isn't specific enough), Measurable (maybe the only criteria you meet right now), Achievable (no waiver =/= achievable), Realistic (lawlz), Time-Bound (your fundme page only says when you are going to college and when you are going to Mars, so I feel like this one is lacking as well).
Like everyone else has said (and I mean it, and they mean it too), good luck. That being said, no one in the amateur rocketry community will hesitate to tell you that your plan isn't feasible, and that you need more experience. The fact that you are asking for money is why instead of being dismissed as a naive kid, you are being roundly abused (which forums like to do whenever they have a good opportunity).
