Startup costs: It depends on how you want to teach. If you made a course through something like Udemy, your start up costs could be $0. If you want to make your own website to sell videos or courses, then you’ll need to spend a little bit on hosting. I’ve used Bluehost for tons of my niche sites. If you’re starting an online business, Bluehost helps you get started with cheap hosting and a .com domain name. Try them out to get your online business going.
If you want to clear some space out in your house and have a big stack of books you’ve been holding onto for too long, you can make money selling your books and textbooks online. Stores like Half Priced Books and others will give you cents on the dollar for each of your current books while you can check what your book is worth by simply entering the ISBN number on Book Scouter.
Be professional. When you submit a résumé, don’t type it in ALL CAPS and please don’t avoid the caps lock like the plague. Know how to use it without looking incompetent. Write in complete sentences with proper grammar. Of course, there will be exceptions, but even with the exceptions, you must keep it professional. You’re building their view of you.
