Graphic Design Brief
We are looking to get a much better graphic for our design. Our clients main business is pump repair, engineering, service and repair. We need good graphic update for the low key design. This design needs to stand out and have good graphics to suppport it. The front cover should have a happy technician with their company logo. This is industrial and should show the same. The word document attached has text changes that need to be completed as well. Please ask any questions before submission of the design concept. There will be a second flyer design and the winner of this will be selected to update that design as well.
UPDATE: Client requested we place some images on the rear panel of these tupes of tanks (NOT THE ONE WITH THE METAL FRAME) https://stock.adobe.com/search?filters%5Bcontent_type%3Aphoto%5D=1&filters%5Bcontent_type%3Aillustration%5D=1&filters%5Bcontent_type%3Azip_vector%5D=1&filters%5Bcontent_type%3Avideo%5D=1&filters%5Bcontent_type%3Atemplate%5D=1&filters%5Bcontent_type%3A3d%5D=1&filters%5Bcontent_type%3Aimage%5D=1&k=plastic+tanks&order=relevance&safe_search=1&limit=100&search_page=1&search_type=usertyped&acp=&aco=plastic+tanks&get_facets=0&asset_id=471919703
Updates
Client requested we show tanks like these (not the one with the metal frame) on the back of the flyer as they also sell and fabricate plastic tanks. Flat bottoms only. See this example. We can group them close together for saving space.

Client provided these images for their flyer. They are hoping we can incorporate a few of them into the design. This is the custom fabrication of tanks they do.
