When i askd for a call, so isay, if you agree toa meeting with me er to talk about your digital marking needs, i will take you for lunch or to keeler shots - and promise to be somewhat entertaining. I'd just love to give you some ideas you're free to steal. Would you be up for a quick call or meeting? That basically it's making them an offer tha they probably have never heard before.
