If you have a small business and a business checking account, you might want to open an ING Direct Business Savings account where you can earn some interest. There's also a $50 bonus.
Here's the link to ING Direct's promotion page
According to the offer's small print: "Bonus is deposited at time of new account opening, and is available for withdrawal after 30 days. Bonus is available for new Business Account Customers."
You'll probably earn more interest than in your business checking account, but the ING Direct business savings account rate is currently only 0.50% which is quite a bit lower than the Orange Savings account rate.
