This is hard to write, but I feel as if an honest question deserves an honest answer. You don't have enough money or experience to start this company. You need a much better design for your website and your purchasing decisions to date lack business accumen. Spending $2k on SSDs is not a wise choice, and throwing more money after them is not wise either. You underestimate the amount of money it will take to launch this by at least one order of magnitude, if not two, and you overestimate the willingness of investors to invest in pre-traction startups.
My advice: Take $300 from the $3k and try to make $350 with it. If you fail, try again until you either have $0k left, or a business that makes some sort of bare minimum profit.
If that doesn't sound fun to you, then get a job at a startup and learn as much as you can while you are there.
Sorry for the hard words, I was in your position at some point in my late teens, and I wish someone had told me the realities.
(The good side is that you will eventually make it. Just keep working hard.)
Best of luck.
