I wish I could say I found them remotely, but alas these were literally friend-of-a-friend type deals.
More details: One of them was a bakery that was taking all its orders on paper, so I developed a simple but powerful system for them to track their orders in a database, and other was a small investment shop(read: a pair of people managing a millionaire's money) who were looking for a way to track trades and get on with the important stuff rather than waste two hours a day updating an Excel spreadsheet. My biggest problem I haven't been able to leverage these jobs into continuous passive income.
eg Moonlightwork sounds like it should be for moonlighters like this, but looks to be full time jobs.
