Highest A7 iso for paid gig?

Would I get lower noise by shooting with a lower iso and then increasing the exposure on post or will I basically end up with the same noise?
Yes, lower ISO = lower noise in the general case.

The reason is quite simple.

Lower ISO images are created to adding multiple high-ISO images together.

Since noise is a random event, it's unlikely to appear at the exact same pixel in multiple exposures.

So adding exposures together and then averaging the results reduces the noise.

That's just the way the electronics works. Post-processing software is a different subject.
