Had to look up hinky as I have never heard that word before. However, that word works here, this is very hinky.
A common scam and many red flags here.
Edited: Did a quick google search and there is nothing on the web for either of these entities, no websites, no reviews, nothing. I did find valid corporate entities in these names in the state of Florida, one established 9/2018 and the other 12/2018. However, that means nothing because scammers will steal the use of legit corporate names to use as their own.
The scammers will pretend that the escrow company is legit too but that entity is going to be the same scammer. Legit companies take any proceeds out of the selling price. Sellers do not have to put money into escrow.
I look at all of these out of the blue companies as scammers unless the evidence proves they are not. Nothing legitimate is found about these two entities so I am sticking with it being a scam.
