okay, first of all the directgov site is PANTS
Think about where else you can advertise:
doctor's surgery/HV office
library
schools
preschool and groups that you don't attend
put a poster up in the back window of your car
make sure that your posters/cards show that you are Ofsted-registered (but don't put your Ofsted reg number on them)
think about what is your USP - unique selling point - eg do you offer early starts/late finishes, do you offer overnight care, do you have a FABULOUS garden, can you accomodate shift workers, that kind of thing, and work your USP into your posters
Do you have a Childcare Development Officer, they might be able to help you too
A lot of folks are quieter at the mo, what with the recession
Do you get together with local CMs, go to the Toy Library, get your face around the area, so that fellow Cms get to know you
All my work has come from word of mouth
Good luck
