Chances at NYU Stern [3.77 GPA in IB, 1500 SAT]

The businesses are largely informal, one being an import business where I would buy bulk e-bikes from China and resell for a profit, I did 50k revenue and 23k profit. With that said, there was no LLC or any official documents aside from my receipts and messages with customers. My second business was far less successful, it was a clothing brand catering to e motorcycle riders, Tslgear .com. This did 5k in revenue and 2200 in profit. Would this still look good on my resume? And how would I go about proving something like this without any official LLC’s/legal documents.
