my name is xinyu zhang and I am doing market research and need some help from those of you who own a wine cellar/fridge product if you live in the San Francisco bay area.
I'd like to invite you to my research study in San Francisco from Aug 2 to 6. You will be paid $100 in cash for sharing your knowledge and opinions about wine cellar products during an one hour session of interview.
Please contact me for more details at email@example.com
I am looking forward to talking to you soon.
