Homeowner wanted to secret shop real estate agents to sell your home (San Diego)

We're a market research firm representing a real estate brokerage looking to open up in San Diego.
If you're a homeowner in San Diego, we'd like to pay you $500 to interview a real estate agent to sell your home.
You do not have to list with them.
We'd like you to take detailed notes of their presentation, costs, guarantee, listing contract, follow-up procedures and more and report it back to us so we can have better insights on our competitors.
You do not have to have a real intent to sell, only to play along that you're thinking of selling and that you're interviewing agents to gather all the information you need to make the best decision on how to hire to sell your house.
Please email if you are interested and we'll call you to make sure you're a homeowner, explain what we would like you to do (that's all legal and ethical), and then you can get started.
