Well if you are not willing to provide the information requested, you may not get specific information on how to do what you want. I did  not notice those little symbols by your name when I read your question. So you are a Top Seller, Prime User, and a Vendor. I checked your store and put you on my list of vendors not to support because I was only trying to help you and your response leads me to believe you would not value me as a customer. CSR.

It has been my experience when asking a question if you provide the basic information as I requested, you are most likely to get answers that will help you including, links to why you might need to use certain settings to get the results you want.  With the right hardware and settings I can get a high quality render on my machine in less than 15 minutes, (and it can be printed) while others may render the same image and it takes 4 or 5 days to get the same results I get.
