Atty to Review Separation Agreement before I sign

I do not have an Atty retained.
Wife does.

We have agreed on a Separation Agreement, but have yet to sign it.
I obviously want an Atty to review it.

What is normal for the time it would take to review and the cost ?

I ask as I’ve called 2 Attys I’ve had consultations with last year.
Atty 1 says One hour - $175.00
Atty 2 says $500 down for a min of 2 hours, and that sounds like a ‘starting point’.

So close to ending this mess.

Many attorneys charge by the hour, so it should not be too costly to have an agreement reviewed. The quotes you have gotten sound reasonable.
