The honest way to frame the H-1B alternative isn't “bad” — it's “later, maybe.” Price the later and the maybe.
If the candidate's record supports it — and for the specialist profiles on O1DMatch it already does — the petition files any day of the year and premium processing decides it in 15 calendar days. Your part is one page.
Not either/or: some employers run both — engage the person on an O-1 itinerary now, register for the lottery when the window opens. Nothing about the O-1 forfeits the H-1B later.
