I'd expect 400 new customers enquiries from 40000 black and white leaflets. I suppose you might get better than that from colour but I've never tried.
Good luck.
when was the last leaflet drop ?
side note: did you ask your programmer about the database ?

We never stop leafleting. We do 500+ per week.
I did ask him, he has a lot on his plate at the moment but said he would 'give it some thought' I will see him this week and enquire again.
