Design change needed for medicine box design

I have a medicine box that was previously designed for me that measures 4"x3". I need you to make some small text changes on the box that is as easy as replacing some old text and inserting some new. Probably a 5-10 minute job. Also, I need you to take that same dimensional layout from the medicine box and overlay a slightly different design that was already prepared. Basically, I am creating a 2nd box of the same size as the first with some graphics that I already prepared. I need you to overlay these graphics and make sure everything is formatted properly so that I have some print-ready artwork for the printing company. I will provide a PDF of the medicine box design.
