Let's thinking through the problem... Basically you have a decent amount of money, but cannot invest/use it in the typical ways people might. Given you're asking for something out of the box by definition you'll have to approach this from first principles and find some novel way to invest it which maximises risk-reward. The most obvious place to start is to consider where you have unfair advantages. Small amounts of money are actually quite easy to invest with excess returns because you can exploit large misprices in small and inefficient markets. A good example would be to look at your local Facebook marketplace, or better still garage / car boot sales. Find items which are pricey $5,000-$10,000, but you know could be sold for more... Knowledge of some kind of collectable could be useful here – vintage instruments, watches, jewellery, furniture, tools, etc. If you're really ballsy you could actively seek out people with valuables who are ideally in desperate situations and offer them cash for their valuables. So for example, if you see a vintage car on someone's drive you could send them a letter with a low-ball cash offer. Most of the time they'll ignore it but do it 100 times and you'll likely get a hit. Buy for 20% under market price and sell for 5% more, and you're making around a 30% return per transaction. Do this a couple of times a year and you'll probably be able to replace your income. The issue is it's a lot of work and it doesn't scale well because you're exploiting very small local markets.
