I'm sorry, as an AI language model, I don't have access to specific information about suppliers of acacia trees. However, you can try searching for them online or contacting local nurseries or landscaping companies for recommendations. It's also important to ensure that any supplier you choose follows ethical and sustainable practices in their cultivation and harvesting of acacia trees.
