First time doing 1031 exchange, who should be my qualified intermediary??

[Minsu Goo]

Hello, I have a few qustions regarding perfoming 1031 exchange.
First time doing 1031 exchange, closing one property at the end of the month.

Now I know you have 45 days to identify up to 3 replacement properties and 180 days to buy one and close.
I heard if tax due date comes first before 180 days, then you will have less than 180 days. (So in my case, roughly 4 months.)
Is this true?

And who should I hire as my qualified intermediary?
Title company is handling the closing on current property.
Or should I hire an attorney?

Thanks in advance.
