Fees will vary, substantially, depending on where the practice is located.

I have a minimum charge of $ 400.

I won't charge extra to just enter the amount of the EIP(s); that presumes that my client provides the info.  If they don't "know" what they got.... my first instinct is to fire them 😁

I will NOT be attempting to track down what they received for them, but IF I did (there's always an exception) - they would pay royally for my services.
