A friend in Boston made a living doing this. He had lived in the Netherlands and was fluent in Dutch. He contacted companies who sent people to the Netherlands to work and live, and offered to provide not just his language expertise but important information on Dutch culture and living in the country. It worked. If you’re from or have lived in another country, consider channeling not just your language but your cultural expertise into a new career.
After all the work you've put into starting your business, it's going to feel awesome to actually see your idea come to life. But keep in mind, it takes a village to create a product. If you want to make an app and you're not an engineer, you will need to reach out to a technical person. Or if you need to mass-produce an item, you will have to team up with a manufacturer.
Take it seriously. Yes, you’re applying for an online job. Yes, you can do the work in your underwear, but that doesn’t mean it’s not a “real job”. You must treat it as such or they aren’t going to treat you as a serious candidate. You aren’t the only one who wants to work in their underwear. In fact, the competition online is likely higher than it is in your local area.
