Hi NewGuy :-)
There`s a time for research, and a time to "get your feet wet." The advantage of either auditing courses in a community college, or putting up an item on something like Bonanzle is that you don`t lose much of anything if you make mistakes.
Find something to sell. It can be anything. It can be a one-time item, perhaps something you have at home you`d like to get rid of.
Use that single item to create an account with Bonanzle, take some photos (with a digital camera, not a Web cam). Upload those photos. Create a heading title for a basic "What`s this?"
Write a bit about why what you`re selling is valuable, how it might be used, and what`s the condition (new, used, beat-up, etc.).
As you go through all these tasks, you`ll quickly come to understand the process. And that`s what you`re asking about---process.
The problem for many people is they get so caught up in the process, they forget that there`s more to a business than just the day-to-day tasks. Why do you want to get involved with ecommerce? How will that improve your life?
With so many people losing their jobs, they often turn to ecommerce as a replacement job. But running a business isn`t a "job." You`re suddenly the boss of the whole thing. That means you`re responsible for the success or failures, and you`re responsible for solving whatever problems you encounter.
There`s nobody to tell you what to do. But you can find lots of people with advice as to how to solve specific and particular problems you encounter. Therefore, your first step is to go out there, get something started, and encounter "some problems." :-)
When you have particular problems, it`s a lot easier to get answers to those specific questions. Make sense?
