first get yourself an autoresponder. this is the most important element to scaling your business. you need to build your email list. you don't necessarily have to have a free give away, it can be paid or it can be a biz op. make sure you integrate your autoresponder to your squeeze page so you can capture leads. use techniques like banking clicks to grow your list faster. blog your tests, efforts, and successes. finally, develop an effective back end follow up via personal connection and automated processes.
i personally use aweber and recommend it to serious marketers ready to scale and improve their business
