Crazily enough PayChex has told us that the real solution here is for us to "sign" the person over to a contracting company so we can hire them thru the contracting company for the evaluation period. Yes we'll pay more for them since we have to pay that company's markup but we won't get gone after by the IRS. And, yes, it adds another layer of BS / paperwork. End result? We've hired no one because of this - its too hard to vet engineers without seeing their work. Sigh.
