I hope this message finds you well. I wanted to follow up on my previous inquiry regarding the ramps. I'm very interested in purchasing four units and would appreciate it if you could provide me with a detailed quote, including the shipping costs to Australia. This will give me a clearer picture of my budget and options moving forward. Additionally, if there are any specific details or requirements you need from my side to facilitate this quote, please let me know. I look forward to your prompt response, as I am eager to move ahead with this purchase. Thank you for your assistance!
