Drupal Commerce Discount Rule

Hello, Our webshop is built with Drupal Commerce (Drupal 7). We are currently implementing some discounts to our store. We currently have the 'commerce_discount' module installed. We would like to create a simple discount rule for the following situation: - First product 25% off - All other products 10% off So if somebody buys three products, the first product has a discount of 25% and the two other products have a discount of 10%. All products have the same price, so we don't need to add additional validation to the rule. We are looking for someone who has experience with Drupal and the Drupal Commerce module who can create this discount rule.
