Yes, it is just a matter of good sales and marketing, in the same way that building your online software was just a matter of programming. It's often said that it's better to have technical-only founders, because it's easier for them to learn the non-technical aspects of business than it is for non-technical people to learn the technical side. This is true, but it's predicated on technical people actually putting in the effort to learn. I'm still learning sales and marketing myself, so don't take what I say as gospel, but I think the solution to your problem has two parts. The first part is an intensive, non-sustainable effort to win your first few customers. See edw519 for how to go about it. After you win your first customers, things will get easier, by which I mean possible. Seeing other people have success with your product is an essential part of the sales process, so once you get your first few customers it won't be like pushing water up a hill anymore. It will be like pushing large rocks up a hill -- difficult, but not impossible. The second part of your solution itself has two distinct parts: selling the problem, then selling the solution. You have to separate selling the problem out as a separate activity. Blog posts are part of this, but won't be enough by themselves. You'll have to figure out the rest on your own. Once you've sold the problem, you're ready to sell the solution. Pointing to other people having success with it will have much more effect than any of your logical reasoning as to why your solution fits the problem. When people say a good product sells itself, they don't really mean it. It's like if we programmers say that with a good requirements document, software writes itself. What we really mean is that with a good requirements document, someone who knows what he or she is doing can write the software with minimal struggle and creativity. Your next challenge is to become somebody who knows what you're doing in the sales/marketing area. Until you do this, it will be as hard to bring in an appropriately skilled sales/marketing person as it is for a non-technical founder to bring in an appropriately skilled programmer.
