The right approach could be to write an email to a relevant on the web publisher with some particulars of the post and wait for a response. Most consumers will think that the custom brochure is free while at the same time you get free marketing points through them. Those business sectors which carry their own industry-related publications are perhaps less likely to use locally based leaflet distribution to customers for general marketing, but of course they may well take the local approach to boost trade at specific times.
