Both are pushy to the extreme - they are sales people on commision.
Ask your potential customers if they use any publication before you advertise in it. You will save yourself a fortune. People advertise in the Yellow Pages because they feel they need to, but unless you are measuring and making sure you know where your customers are coming from you are wasting your money.
To prove my point, take your Yellow Pages and look under Insurance. There will be over 100 PAGES of insurance companies advertising. There is no way you will ever convince me that all of those companies make money from their Yellow Pages Ad - I guess over 95% of them are wasting their money
