I need 4 x A4 PRINT QUALITY posters designing

I need 4 posters designing which are A4 in size. They must be designed to be of print quality. They are going to be printed on adhesive vinyl. The posters will be used simply to stick on shop windows wherever we introduce this product to the marketplace. Just to gain awareness of the product. Each poster will represent a large worldwide beverage brand. 3 x beers posters and 1 x water poster. Please make sure you allow in your price for various revisions until the file is as we need it. I will require all of the original files. in PSD, Ai and the fonts used for the file. There are lots of images and information found online but I will send you a brand toolkit which will explain the brand. I will also include some images in a google drive file to give you an idea of what the brand represents. The job must be confidential, all work done promptly. You must not use the work in any of your portfolios. You must speak English and your bidding price must be your final price. I do not want to deal with people that bid a low price to get the job and then increase it afterwards. Please take into consideration that I may not always be able to reply immediately to queries due to my job.
