When you see the actual work involved, it takes an hour or two to organize all the documents and fill them out. Is $750 for that little amount of work justified? No. Does it get your app processed faster? No. Is it possible the lawyer missed something? Yes.

If you do it yourself, you can look it over two, three times, and make sure everything is perfect before sending the app. Lawyers don't really do the work, their paralegals do everything.
