Get a credit line. It is not uncommon for most startup businesses to rely on a line of credit. The American Express Plum Card, for example, offers a 60-day term for payment rather than a typical 30-day term. Some banks or credit institutions offer credit designed to allow growth in the early stages of business. A word of caution: to keep from getting bogged down in debt when you are trying to expand a business, keep purchases to a minimum.
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.
