I mention The Hollywood Creative Directory quite often in my posts. It’s a great source of contact information for nearly every production company in the United States. You can buy a hard copy from Amazon.com, which I highly recommend. Having the hard copy allows you to go back to it often and send out query letters over a long period of time.
However, I’ve had a few people ask me if there was a cheaper way to obtain the information in the HCD. If you go to the HCD website, http://www.hcdonline.com/, they’re now offering a subscription service which is less than $20 per month. Join for one month, go through every company and copy and paste the information into a Word or Excel document for later use. While this will take a bit of time it will be cheap. Just make sure you cancel your subscription before the month ends or you’ll be auto re billed for the next month.
