Cover for you.
Hope you will like it. Let me know if anything needs change. And for the contest, i will suggest you to choose a winner already and work with him, give him instructions to get it perfect. Because with that budget i don't think so many skilled people will try. I am doing cause i am a food engineer myself. So i liked it. Thank you. You have been so much helpful, made it easy for the designer with your precise description and further tips through comment.
