I would like to be the owner / creator of my own advertising company and have control over 3 or more city billboards to display attractive advertising for character shops / services, is this a possibility?

Already suggested, but i'll add to it. It'd be cool to allow shops and businesses to create their own website to; Showcase and sell their products and merchandise Place orders with shipping companies Advertise job vacancies which players can apply at Display contact details and addresses There could even be an online yellow pages for easy access to addresses and phone numbers. Business owners could also create advertisements for online use. This would cost money (probably paid to the server) and would vary in size.

I reckon i'd be cool if businesses could advertise their brand around the island. This would increase realism and immersion, as well as bringing in customers. This could happen in a few ways; - Customised ads (ie; made by the player) which appear on billboards and walls (advertising space which may be rented/ brought), also could appear on the rear of a bus and inside the trains - Player customised flyers, emails and catalogues which could be sent to residents and customers. These could contain upcoming sale deals and products - Radio adverts recorded by the player, which play during the commercial break (could also be used on TV - if they're in Identity)
