Since my original blog post, I've been involved with a number of projects, and the new ecommerce system has been put on hold.
One of the things I've realized in all this is that there may be something else I can do, which will be quicker to set up, will help a great many people, and give me greater insight into my intended audience.
Pre-built websites.
I've talked to a number of folks who like the idea of having their own website, but do not already have a product or service to sell. These folks, when questioned about the type of website they want to have, typically respond with something like, "I don't know. Something that makes money."
Because of my 9 years of experience online, I know the types of websites that make money, and what it takes to build them. (This is the reason I decided to offer a service to build websites for folks.)
