As part of my self-referral process, I have partnered with a friend of mine who is a business coach. We are running a monthly networking event as co-hosts. He has proposed printing up a bunch of postcards and will be personally going door-to-door meeting local businesses. The front of the postcard will have the details of our event. the back will be shared with half for his promotions and half for my incredibly engaging text. I would like to get your input for text that includes a "free no-obligation" something.
