W-1's top town is about 28,000, and they have level max Hotel, Residence, Tailor, Gen Store. Gunsmith is 8 or so and I'm not sure about their Town Hall.
Gunsmiths go upto rank 15, but frankly past 9/10 isn't needed yet since players aren't high enough levels to use the higher rank weapons.
iirc the rank 15 weapons are for L 70's
Once my towns stores are 10/10/10 I will probably tell them to stop donating and just build from money the town takes in via selling and visitor donations.
The rumor about the Sheriff is that a certain rank of Town Hall is needed, but we'll know about it long before it goes live.
