So very complicated to list a product

Wow, as a new seller on amazon, I am astounded by how complicated it is to input information and to list a product for sale. For example, having uploaded many photos to use for the listing, I have later seen a requirement to have the photo labeled according to your exact specification. It would have helped to have that indicated when I was in the motion to upload the photos. Everything without exception is a challenge for (me) the average under-educated computer idiot. I need an amazon assistant on the phone (a real person, preferably from these united states) to walk me through the process line by line and to provide some classic old fashioned handholding. Getting help by chat is cumbersome, the data submitted takes a great deal of time to be reviewed and approved, and the specificity of amazon requirements to be on the site are obnoxious. Just saying, I am inclined to bag the whole effort and ditch amazon for good (both selling and buying). Unbelievable that your site has such specific data input, and then to save? No, doesn't save; input lost. Do it again. Obnoxious.
