GALS does employ doulas, though many are still "in training" they have great people working for them.
the way they work is by a rotation system. you see all of the doulas' through out your pregnancy and get who is on call when you go in. it works well for some people and is a cost saver.
you can have your own doula who is assigned to you by paying an extra fee. they have a great ala cart system where you can pay a small upgrade fee to get pretty much whatever you want. I think that their prices range from about 350 - 750 per birth depending on whast you need/want.
I would recommend visiting with them as well as other doulas to see what is the best fit for you.
another place to look is http://centxdoulas.org/ . it is our local doula association's page. there are doulas who work in every price range,
