Hello. You are a professional business coach with an MBA degree. Help me find a business idea that will work based on what I have on my hands (not much!)
So, my limitations:
- Very small amount of money I can spare. Probably not more than 1-2k dollars. Our entire team was laid off and out entire field is dying, every opening, if any appears, is instantly flooded with hundreds of resumes, so statistically one really does have to apply to ~400 jobs to get one and the average rate at which those new openings appear is like once a week or so. 
- I am in a terrible situation in which I can't tie myself to my physical location. Therefore I can't do 99.9% of business ideas which are all "do this niche but in your city". My business has to be fully online and not have to do anything with "local" clients or anything.
- My main skillset is VR/AR development in Unity and as I've already said, this field flopped entirely. There's zero interest among investors, it seems.
- I need to start generating some money asap or else I won't be able to feed my family soon
- I have no local market due to the previously mentioned problem of not being "located" anywhere permanently
What resources I have:
- I'm still a developer with C#/.NET, Unity, SQL and (some) web knowledge. I know this stuff has brought people immense money in the past when used precisely to satisfy what the market needs.
- I speak perfect Russian and English
- I am located in a relatively cheap place where I can survive on around 600 USD per month so if I get to do some business that starts to return investment early I can just reinvest all of it back instead of eating through it immediately despite the very tragic financial situation
- I am laid off, therefore I'm free to work on that business full time
- My legal entity is located in a very favorable tax jurisdiction and only have to pay 1% income tax
- I have connections in a furry community which is known to be a niche but very loyal and paying one
- I have some CAD and fabrication skills, I could potentially produce stuff on a small scale (model and 3d print things)
- I have some experience in video production. I am very good at editing videos, but none of my channels were successful, with the best one being my TikTok with ~10 million views and 20000 followers, which might sound like a lot, but would probably convert into a really tiny following on YouTube. By the way, I've also had a YT channel, but that didn't get anywhere above 400 subs.
Not all of those advantages have to be made use of, but all of the limitations should be taken into account. Feel free to ask questions before answering if I forgot to mention some detail that you consider crucial for business planning. Please provide specific product/service ideas. "You can code so I suggest that you write code and sell it for money" is a truism and it is plain nonsensical as a piece of advice. I know that if I can code I can code for money. Please be more specific. I also think that you've missed the part where I said that the entire industry flopped, I'm NOT the only one out there left with no job and looking to "code for money". I understand that the most crucial piece of advice for any business idea is to find a problem of a certain community and solve it, but I seem to struggle with that, which is exactly why I'm asking for your help.
