Selling graphic T-shirts is big business. Customized T-shirts with clever sayings or graphics are ideal for online sales. Sites like Teespring allow you to sell customer shirts. Teespring’s unique model allows you to design the shirt and get buyers lined up to purchase it. This saves you from the initial investment in stock and the time on processing and shipping orders, though you’ll likely make a smaller profit on each shirt sold.
If you decide to upgrade, you’ll be able to move your freebie domain to a full .com domain name. That domain name will cost $14/year, which is standard pricing for domains. All the content will be moved over to that domain. Hosting is included for free in your WA membership. If you decide to leave WA, you can move all your stuff to a new host whenever you want.
Continuing with my example above, in my article about roasting green coffee, I can find green coffee sellers and promote their coffee on my blog. In an article about home roasting coffee machines, I can promote my top 3 favorite home roasters. After I sign up for those affiliate programs (they are free to join), I just place my affiliate links in my content, and it automatically tracks sales.
The thing that I really like about WA is that even though I feel I have some good experience now (not an expert yet!), I realize that I can get help from someone with more skills and knowledge than I have at any time. There are experts within WA, many with MUCH more experience than I have that I lean on for support and to advance my own personal skills.
Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
