I require a flyer for a new service my business wishes to offer

Description

My business is a German car specialist, and a VW group workshop. We're looking to venture into ADAS (advanced driver assist systems) calibration and maintenance. As such, we're investing both our capital and our time into this and we feel it's only fitting we have some new marketing materials to go along with it.
We're looking for a professional looking flyer that's as informative as possible, without sending the reader to sleep.
We're also considering developing a new trading identity purely for this venture, however this is something to decide in the future.
The company is www.eastyorkshireretrofits.co.uk. Some examples of the manufacturers we're in talks with for our equipment are Texa, Launch, Topdon, Autel, Hella, Bosch.
The flyers will be handed to local garages and workshops. They'll also be sent along with our customer orders
