Payroll Protection Program (PPP) under the CARES Act

PPP sounds great because you get a loan for 2.5 months of payroll, and then it's forgiven if you don't let people go.  Has anyone tried to get one?  Our business has PT employees: $7.5k of payroll in 2020 Q1, but only $15k of payroll for all of 2019.  What will they use to determine how much can be borrowed/forgiven?  

 

They say your business has to have been affected by coronavirus?  What's the standard of affected?  I wonder if it's worth messing with the gov't red tape if your monthly payroll is only $2,500.
