Hi! This would be more of a local South Carolina service. I've had some experience creating balloon arches and would love to help to decorate for your next party/event. I listed the duration as 3 days because it may differ depending on arch sizes, as well as you actually receiving the arch. I also will say this arch was bought from Amazon then I put it all together, that would be included in the price. I'd love to discuss more details and clarify anything!
