loan with no credit

hi i’m 18 years old. i have my own apartment and car and i get paid biweekly about 1200. i am having to pay a lawyer and need a loan of 500$ and i have no credit but would be able to pay back the loan within two weeks. any online places you’ve used or tips on what i can do? my bank only will give me a secure loan where i give them 300 of my own money and then i have to pay that back so it’s not really useful and i’m having to come up with this money fast 😭. please any tips or info
