Mailing packages nowadays is not so well received. Most people want a digital package, half of them don’t have anything to play a CD or DVD on! CD’s are the new 8-tracks!
Most pros nowadays tend to get a website built with all the relevant information and demos on it (or build it yourself if you have decent website skills), contact information, booking calendar etc..
Then all an AD needs is a laptop or tablet to get your info. Plus, the same package will work for restaurants, bars and weddings etc.
