China-Based Assistant to Contact CHEO Expo Sales (Hainan, August)

I need a China-based, Mandarin-speaking assistant to help me attend the CHEO expo taking place in Hainan this August (https://cheo.sinohealth.cn/). You do not need to be located in Hainan; anywhere in China is fine, since the work is done by phone, WeChat, and online forms. The main task is getting in touch with the expo's sales department to find out how I can attend, and then helping me communicate with them on an ongoing basis. The registration and contact forms I can find are all in Chinese and require a local Chinese phone number, for example: https://app.jingsocial.com/microFrontend/forms/jsf-forms/details/aFWV5jGKJoHmhN2LqoxPbQ. You would fill out the necessary forms, reach their sales team, and relay information back to me in English. This is urgent, so I need someone who can start right away. Contract will be hourly.
