Online tax filing software needs advertising banner for e-newsletter

This is what a business in Australia was looking for in their banner ad design

I need an e-newsletter banner advertisement with the dimensions 564 x 250. My business is named Rapid Return and is a new online tax filing software which helps Australian individuals receive their largest tax refunds at a low cost.
