Hi Richard, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. Yes, you need to actually sign using a black pen on a sheet of white paper. Then scan the signature and then extract the signature deleting the white background and then make sure that the image is saved with a transparent background as well. If you have your signature now I can do this for you and then give you the finished product which is your signature with transparent background.
Please let me know by replying to me here so that I can help you further.
Thank you for writing back. Yes, we can do the remote session so that I can do the procedures directly using your photoshop while you watch on your screen.
