Looking for a Japanese/Chinese or Japanese/English interpreter in Tokyo this March.

Hi. I am Hubert. My team will be attending a trade show called Tokyo Good Appliance in Tokyo from March 3 to March 6. We are looking for a Japanese/Chinese or Japanese/English interpreter for the 4 days. It would be better if the interpreter has a background in home cleaning appliances such as 掃除機, 水拭き掃除機. Please feel free to recommend. Thank you.
