i dont know if this would help or anything, but what about looking/enquiring with other bookkeepers? meaning pretending to be a customer looking for a bookkeeper and ask around, prehaps search for bookkeepers etc in yellowpages etc, that way you'll get an honest answer too, even when you do your course ask them what to charge or where to look??

Dont know if it'll help but its an idea, goodluck!
BTW: wow at being 33 1/2wks already, time is flying past, it feels like only last month you were announcing you are pg!!
