I wouldn't try it again. I one tried posting a special around Christmas time in my neighborhood, similar to what you describe, it was also when the economy here was very slow, and nothing! Those are the clients you probably don't want. I one time did "just the bathrooms and floors" for a client, and by the time I was done I felt like I did all the hard work, and got paid very little. I try to get the clients that are going to give me the most hours, and the highest hourly rate. I think anyone who is serious about a cleaning service will just hire you to clean their house. the only other thing I might do is tell people I am willing to cut some corners, or hours to fit their budget, if they seem like they will be a good, regular client.
