Quick design job - need medical brochure reworked

Hi there, I need a flier for a medical product reworked. I have attached the original brochure ([login to view URL]), and a brief for the new brochure (Curtain [login to view URL]). I'm not sure what size the document should be (A4 or A5?) - I will be guided by you on this, and it will depend on how well the information and images fit the pages. The look and feel of the flier needs to be contemporary but clinical. Images of the product are attached - use whichever images you think look best. I've also attached 'before and after' photos of an actual clinic here in Australia - one 'before' photo and one 'after' photo must be used on the flier, but you are welcome to use whichever ones you feel look best. It would be greatly appreciated if you could touch up the photos to make them look professional. There is a PDF of the product label included in the documents that I'll send through to you (Curtain [login to view URL]) . I'm wondering if it's possible to fix the [login to view URL] image so that it shows this label instead of the current chinese label? I'm not sure if I've suggested an ideal layout in the brief - please feel free to layout the information in another way if you think it will be better - my brief is just a suggestion. There's quite a lot of text, so if you think there's a better way to arrange it on the pages, please feel free to make suggestions. You have full creative licence!
