You can check with WF, but Chase do have that service. You will need to send original. Send the original by FedEx or other reliable carrier. The bank has own format and contents for the document that you are seeking. Your draft may not work unless you are expert in legal languages. 

If your bank doesn't provide that service, then you will have to find a local attorney who does that job. Google for an attorney, or your bank may refer one. Usually it may cost you around $100 to $200 for that job.
