Ticket Liquidator For Hamilton?

Heading out to NYC next week for an improptu business trip and was trying to score a single ticket to Hamilton. Exploring all of my options right now, incluiding Ticketmaster resale, StubHub, cancellation line and line-sitters. I came across a site called Ticket Liquidators that seems pretty legit, but was wondering if anyone out there has experience using them to purchase Hamilton tickets. The price of the ticket is slightly cheaper than the resale I've seen on Ticketmast and StubHub. If anyone else out there has recomendations for getting my hands on a ticket, fee lfree to share. Thanks in advance!
