Spy differences

Tried searching. Couldn't find anything.

How does spying work exactly? And are there differences between the types of spies depending on the job/company type?
I know there's the Army, Law firms, and TV networks. Are there more?

I know eventually I'll grind through the army job just wanting to know more of the specifics. Thanks

There are 2 types of spies one that views your target's stats and one that views your target's money on hand (also there are specials that can do both at the same time)

For example: Army and Law firm, you can view a target's battle stats for 10 job points (army also requires $5000 for some strange reason)
A Hair Salon, you can view a target's money on hand for 10 job points.

At a TV network, you can view a targets battlestats and money on hand for 15 job points.

Thanks, and there's a chance of not getting the stats, right?

Correct. Or just a few, and sometimes you have the math the difference:’) or guesstimate.
