Become a good pickpocket, then steal the key from Rizzette after dark. 
Note: Sneak into his room with him. Sell Rizzette either the camera or a clock part,
then go into his room and steal the item back. Repeat this as many times as desired.
Then, go to the Inn and ask the Innkeeper for a week's stay. Continue to sell 
Rizzette the item, steal it back, and sleep in the Inn for the night. 
Rizzette will have a new supply of money every day.
