Page 7, panel 3 should be more like "But she always told me with a smile that she gained strength from the food that I cooked" since it's talking in the past tense.
Chapter 17 was stolen from Edelgarde Scans. You can find it on their website and compare. This translation was ok. Grammar could use some work but it was understandable.
Was there an error in translation? 5,000 gold isn't a big leap from 3,000.
edit:
I looked at the raws. It also says 5,000. I wonder if the author messed up.
