I agree with both BB's pricing and Abdullah's advice.
BB is likely looking at it as tech name and 'ba' is not a very desirable suffix for a keyword hack.
Many would pronounce it Duh-Tah Bah. So BB may have also looked at it as an invented name.
But.............
It means 'dating' in Spanish. That's a pretty powerful keyword.
You might consider listing that on GD premium and Afternic for $3K to $5K
It could take months or even a few years but that would be the way to get top dollar.
Or....... contact
these folks and ask if they would broker it for you and how they would price it etc.
That's what I'd do
