Car broke down looking to borrow 350$ can pay back 400$ by end of month. Zelle, Apple Pay, cash app

My car broke down and I live in Las Vegas, my 2 sons aren’t in the best of health so I need a vehicle to commute them to school and doctors appointments. My mechanic friend is quoting me 350$ for the parts and labor. I’m already dry from rent and other expenses as it is that time of month. My friend referred me to this sub so I’m sorry if I’m not doing this correctly.
