To be honest, I haven’t really explored LeadPages’ sales page templates a whole lot because I tend to design them myself in WordPress. However, when I created my free Pinterest e-book, I decided to create a sales page-esque landing page, which gave more information about the freebie, much like a sales page would. I also used one of LeadPages’ sales page templates to design it.
As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer. 
Committed: Ideally, you want to close the deal when all red flags have been dealt with. In reality, most deals close while critical red flags still exist. At this point, you have provided the customer with a proposal that outlines key contractual terms. When a customer has agreed to move forward with a deal, they are “committed” (also known as “verbal commitment” or “verbal”). What remains is to work out the details of the contract, delivery and payment, all of which have the potential to“undo” the commitment. The commitment may be offered contingent upon certain terms being met.
There are two options: pro pricing and free signup. Signing up is as simple as possible. You just need to create a username and password. Once you get in and start using their tools, you’ll have to upgrade. The free account limits the number of forms you can use. When you hit that limit, you’re requested to upgrade. Otherwise your account won’t work.

Of course, implementing this isn't easy. You need to first develop your stories, then decide on how you're going to convey those stories and at what drip-rate. For example, your first email or two might go out on the day they first signup, then one email per day might go out afterwards. How much of that will be story-based and how much will be pitches?
