As a PR/promotions/communication person, my advice would be this:

1. Collectively you need to raise awareness re doulas through the media. This is not as difficult as it sounds and it's free. Basically, draw up a list of all the pregnancy-related stuff that expectant mums might be reading (pregnancy magazines, general health magazines, health columns in daily/weekend newspapers etc. etc.) or listening to (health programs on the radio, What's Good For You on TV). Then approach those outlets asking them if they would be interested in doing an article/spot on doulas. You tell them a bit about what a doula does and point them in the right direction to other information about doulas then the journalist writes the story. It would also be good if you could offer them a mum who has used a doula to share their birth story so they have both the doula's perspective and the mum's perspective.

2. Once people know more about doulas, it makes the chances of your individual promotion efforts eg. brochures etc. much more likely to succeed.

Cheers
