I agree you have to be a more popular video creator to get enough viewers to earn back the $7500 in a shorter amount of time like under a year if you are starting out making videos for money on sites like YouTube, Dailymotion, Vimeo and streaming on Twitch.
It is possible to make back the $7500 if you have a hard working work ethic where you post many new high quality videos on a daily and weekly basis, and keep learning on how to improve your videos. There are some video creators which started out small, and eventually became bigger and more popular because they had a good work ethic, and are dedicated to created quality videos.
There are also less common chances of having one or more of your videos becoming popular because it ranks high on search engines and social networking news feeds on Twitter, Instagram, Facebook, and Reddit, and celebrities, popular website or many smaller websites like a blog or forum shares your video, TV news, and people use word of mouth to promote your video by sending text messages with a link to your video.
If you live in a bigger city, you maybe able to find enough video editing job postings on Craigslist, Monster, and other job sites where you would eventually earn back the $7500 in a few months if you are good at video editing, and can get new and repeat customers like stores, restaurants, and other businesses which need someone to edit their videos for their business.
