The Business Breakthrough Contest from Visa offers an interesting opportunity for your business: the prize is an evaluation of your business by an expert in your field AND a package of solutions worth up to $10,000 customized for your business based on the expert's evaluation.
To enter you write, in 500 words or less, how your business could be more efficient in one of the five Business Breakthrough categories. There will be one winner in each category. Deadline is September 30.
And don't forget the UPS contest I mentioned previously, and the Ikea contest (deadline for Ikea's contest is July 26, so hurry).
