Form a Grantor Trust. Obtain EIN. Open a bank account with the Trust. Take payment in the name of the trust and do not deposit the checks - cash them.

Declare zero income on the trust. IRS only audited 3,300 of 152,000,000 tax filers in 2018. That's a ratio of 1:46,000 or so, the odds of you ever attracting attention are almost non existent.

You're welcome.
