Best data recovery company in Los Angeles area?

For the first time in many years, I got bitten by a hard drive failure where I hadn't yet backed up enough of the data.
I normally try to stay on top of this, because as a film editor, I have A LOT OF hard drives.
Trouble is, this was not one of my media drives, which I back up almost to the point of anal retentiveness.
And that's probably why I maybe deserved to get bitten, it was my own stupid complacency about a drive devoted mostly to documents.
It's my fault, I let it go too long, and my unlucky number came up, stupid stupid me.

I do not think that the platter is dead, or any mechanical portion of the drive.
I am not an expert but my gut tells me it's the controller circuit board, because the drive continued to offer up little bits of the data at a ridiculously slow rate, then it would fail altogether, then when tried again it would again start showing little bits of the data but would fail when I tried to transfer it.

I hope I am right on this, because if I am wrong, I know it's going to cost a small fortune.
So, does anyone here in the L.A. area have a favorite outfit that can handle my problem that has a great reputation for results?

Feel free to message me privately if you wish.
I go by the name Jeff

I used to use freeze spray on HardDrives back when I was in IT,, sometimes I could isolate a heat sensitive component and keep it cold enough to copy all of the data off.

Did it more than once..

Yes yes, I've done that twice. Didn't work this last time, wish it had.
The other time I tried it I was successful. I just put the whole damn thing in the freezer. Worked well.
I was looking for recommendations for a company.
But thanks.
