• Answer:

  Well as you think it is a good idea you must have some revenue figure in mind so ask for that. Its very unlikely you will get anywhere with such an approach - most companies work on long term strategic marketing and cold calling suggestions won't get much credibility with them (besides which many use agencies who do all the actual buying for them). So try it - see if they are open to the suggestion and then you can negotiate on price - as a base income you need to cover your costs so consider the cost of producing the sign, adding it to your vehicle, maintenance etc
