From Forbes article 13 April 2020

The SBA is concerned that many banks are not taking new customers at this time and therefore not offering PPP loans. Forbes listed in the article several avenues to use.

For traditional banking: American First CU (based on Utah). Website is amerfirst.org. You can become a new customer and apply for the PPP loan online.

Non traditional banking: Both PayPal and Square are accepting PPP applications.
