Rent a car without a credit rating

Hi, my car engine blew up and I need $8k to replace it.

I want to keep driving Uber in Las Vegas, but need a car ASAP.

I applied to Buggy 10 days ago.... still waiting.

Avis requires a credit card or $500 on a debit card.

Hyrecar seems very hit and miss with few options that are decent.

What other options are there?
