It's enough without selling jewelry. Of course, there are two points here. First, 1700 is a shared amount, and second, we might not even find a place to sell the jewelry, or the GM might pull a sadistic prank and offer some random guy in an alley who will take it for 1% of its value.
Or just 1750 for the bow and book. But in that case, I still need to print out the general ledger.
