It looks like a number of folks who use lawyers said they tried to cut costs by preparing the first draft and then having their lawyer look at it. Curiously, this can actually take a lawyer more time to review (and, hence, cost more money). I'd at least consider asking the lawyer for their base form that is the closest starting point for your business and working from that to prepare your first draft for their review.

Virtually any lawyer that does the same type of work repeatedly will have a set of base forms they usually start from. The cost benefit is that they don't have to review things in as much detail because they are already familiar with it (they essentially draft and review documents as diffs from their base form). If you give them a form they've never seen, they literally have to read (and understand) every word.
