I disagree. A good paralegal is worth their weight in gold and you’d be surprised how much information they have. In the US, many have taken courses to get a paralegal certificate that includes research. The paralegal may know what the attorney is thinking or can go to the attorney with your questions and call you back.
Attorneys are generally billed between $100-$250/hr depending on where you live and their experience. Paralegals are billed between $50-$95/hr. All bills are done in 6 minute increments and some attorneys have unannounced minimum billing schedules of .2 minutes. Now, who do you want to call?
