Write a Business/Marketing Email -- 2

I have created a software service and am trying to market it to sell to large multi-family construction companies. I am looking for an appealing and well-worded email that will help us schedule meeting with the company to sell the software. We don't send mass emails and would like emails that can be personalized based on the specific customer we are trying to sell to. Here is our website for the product: www.jcslog.com. We have also attached our powerpoint presentation for you to learn more about the product.
