How to get a conehead in advertising
You want to run an outdoor display advertising company. You have two main options available.
You could negotiate with a Council or a land owner for the rights to sell ad space on their property, sharing the proceeds of the advertising you sell and operating in a regulated manner, so that ads are not too obtrusive. Or you could buy an old car, paint it with the logos of some rubbish company that is silly enough to advertise with you and park that car on the street by a station, taking up a useful space and not making any contribution to stretched public coffers.
