A telemarketing script must not only cover the hard facts of your product but must also convey a branding sense of your company. It must be designed so that call center representatives who know nothing of the product can become instant, professional, and personal representatives for your product.
I have designed complete telemarketing scripts for a timeshare resale company (and then worked myself as a rep). I have also designed sales campaigns for a magazine, a newspaper and a web design company. I am a free lance journalist. You may google my name, Elizabeth Roebling, to find samples of my work, although there are no examples of sales pitches.
