2 sided flyer design update needed

This is what a business in United States was looking for in their graphic design

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.
