Cleaning a nudist's home?

Ok so I'm starting a cleaning business at $20 an hour for each of us and there's two of us. This guy emailed me and asked if I would be interested in cleaning for a nudist. I said I don't see that as a problem since it is his culture and belief. But he asked if we could do the cleaning topless in his home and he would pay us $40 an hour instead. He said he is married and his wife will be at work, but he keeps asking me if we can provide happy endings as well? This just seems to creep me out a bit and was wondering if any one could give me advice. Seeing as I don't want to go to clean his house and he means the ending of my life!!!! Any advice will be nice!
