You should definitely talk to a lawyer, but it's worthwhile going to them _with a draft document already in place_ -- especially if you are starting with one that has been proven for its purpose. Otherwise you may end up paying them to whip one up from scratch that won't be as good. It will cost you much more than the template, trust me.

I have paid a lawyer to create a document from scratch that ended up worse than what I found for free online. So I highly recommend obiefernandez's approach of meeting your lawyer with a template in hand as a starting point.
