Inquiry about Inflatable Dry Dock

As per our online conversation with Ms. Sophie, we received the attached quotation for an inflatable dry dock size Model: 12.2m in external length, 4.1m in width, 1m in depth, and 30cm in barrel diameter. In conversation with MS Sophie she mentioned that an air pump of capacity 1,200W and drainage pump of capacity 2000GPH was included. Furthermore detail to deflate and inflate back end portion was shared via video. This is important to dock the boat. We further inquired regarding production time and dividing payments into 50% advance and 50% upon collection from shipper. Please update as to move forward.
