Change service.price to service.cost. No reason, just like the name better. Change scale to 2. When you set precision and scale on a column, you are simply telling the database how to save that decimal. So when working with money, unless you work at a gas station where they love to use 1/10th of a cent, you will only ever need to save a money amount to the .00 or scale: 2.
