Some lady asked me

I have tried the real estate referal service too.  It didn't work at all.  I say stay away from that one.  I do like the realtors though but I agree that you have to be able to say no or you can get taken advantaqe of.

As for yellow pages, I do very well with it in Calgary.  I have 3 ads in 1 in Maid Service 1 in house cleaning and 1 in Carpet Cleaning.  My bill right now is $3000 / month.  60% of carpet calls come from YP and 80% of maid service calls come from YP.  I do feel that you have to be fairly large before it pays off.

As for other advertising door hangers are great but you need to hit the same areas a few times before they really start to pay.  There are local flyer distribution companies that will hang them for around
$0.08 per house.  I spend about $1000 every quarter on this and it works well.  But, what is really important is that you hang these yourself on the neighbours of the houses you clean.  A good rule of thumb is one house on either side and the three across the street.  This seems to bring in business because they have seen your truck in the neighborhood.
