I love your determination! I got super serious about figuring out how to work from home and ended up scaling up to around $3k or more a month, part-time. It took a lot of time and work, but was totally worth it.
Full disclosure - I had already worked as a full-time freelancer for years, but all of the work required long hours and on-site work. So when we moved from NYC to ATL and was pregnant with my first, I decided to get serious about creating a new career for myself.
First I made a list of all the skills I had from writing, video editing, typing to knowing my way around Facebook. Then I started scouring sites like ProBlogger and UpWork and spending a ton of time on my cover letters and samples and really standing out. I did a lot of research online about how people were winning these jobs, which really helped. I also started telling old clients and various friends I was looking for work at home, and that helped spread the word. Eventually I started doing social media consulting for an old client, became a blog Manager for a marketing firm and started freelance writing.
It's an ongoing hustle finding work, but I much prefer this to the office life. I've also learned how to create extra income through odd jobs like testing websites (literally just clicking around on a site and giving my opinion while my voice is being recorded), transcribing, focus groups, etc. Then I took a look at my budget and got creative about finding creative alternatives to what we were spending money on.
You can do this. It just takes some time and nonstop persistence. Good luck!
