I have been doing some research and found NSW Trustee and Guardian can help to set it up, I think they just help to refer a lawyer, who will charge $220. Probably a very standard document doesn't take much time.
Also rang a couple of lawyers directly, they want to charge by time rather than a set fee, because it can be a complex matter and they want an appointment to discuss further. I guess by that they mean to start charging.
I have since downloaded both general and enduring POA forms (have not validated if they are the correct or current, but got an idea from them), and if I understand the process correctly, the lawyer is there to certify the form and possibly to go over the wordings and explain as needed. Is that right? They are not the attorney.
Your last line suggests you are confused about how this all works.
It would be sensible to pay a solicitor to advise you on this, they can tell you if any plans you might have could be vulnerable to challenges on a future estate dispute or similar.
The reason for the power of attorney is so you can act for the subject, and you must act in their interests. It is important the poa is not defective, or it will be too late to start again, and you should act to avoid future complications.
This is something I think is well worth a couple of hundred to get right.
