It can be quite frustrating sending off a myriad of cvs/dvd's to production houses when you are never sure if they get past the front counter. Often Directors have a favoured storyboard artist/animatic artist who they prefer to use, So getting in good a this level can be fruitful.The production book online is quite handy, (www.filmtvbiz.com.au.). You can subscribe to the online section for only $30 a year, as opposed to buying the book for over $100. Checkout the sections,"Directors of commercials, current abode" and "advertising agency Producers".
Making a good connection with a Director can be gold and most commercial directors have a short or feature project stashed away somewhere. Also, in pre pro of many features these days (where there is sufficient budget) planned scenes are storyboarded or even animated so contacting line producers can be helpful. Not to mention art dept graphics work on fetures and shorts. Contacting Production Designers and Art Directors may see you churning out signage,name tags,fake labels and ficticous newspaper/magazine titles until your wrists are worn. So welcome to the fray berryson. There are many ways to skin the cat. Good luck!
