For many businesses the distribution of brochures or leaflets, is by far the most cost-effective form of marketing. Some do Direct mail and leaflet drops whilst others prefer telemarketing and email marketing.
Leaflet drops or using leaflet distributors is by far the cheaper method of direct mail However, leafleting brings significantly lower response rates. This is because its less targeted. You can increase the response rate by creating offers on your material and also spending the time to create a quality design.
The whole idea is that it allows you to target customers with greater accuracy than any other method. This is because direct marketing whether done by door to door or via the post allows you to generate a specific response from targeted groups of customers.
Get a good printer to provide examples and costings as this is the last piece of the puzzle. Try not to produce your designs on the cheapest material available, as perception is everything. From the time your distributed leaflet is looked at, a picture will be already forming about your company in your customers mind.
