If you don't already have work experience with importing and/or exporting, you will have a longer learning curve.

That alone would probably gain you your first couple of clients. If you keep going with educational seminars and expand your reach to outside your immediate region, you could probably develop a sufficient and ongoing customer base very quickly, but be careful not to outpace your learning curve!
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why?

Off page SEO: This type of SEO focuses on all of the activity that takes place "off the page" when looking to optimize your website. "What activity not on my own website could affect my ranking?" You might ask. The answer is inbound links, also known as backlinks. The number of publishers that link to you, and the relative "authority" of those publishers, affect how highly you rank for the keywords you care about. By networking with other publishers, writing guest posts on these websites (and linking back to your website), and generating external attention, you can earn the backlinks you need to move your website up on all the right SERPs.
