Need it now? Check out Craigslist gigs (help with moving, quick jobs, website help), or try flipping thrift store and eBay stuff. Pros: Quick, no skills needed. Cons: Unreliable and more time consuming.
Need it reliably? Work on a business and work your ass off in your spare time. Pros: Easy to make more than $2000/mo if it goes well. Cons: Will take a lot of time and effort to maybe work out for you.
Alternatively, invest in a property. Pros: Easy $2000/mo through rent. Cons: Lots of upfront investment & research needed to not screw yourself over as a property manager.
Personally I'm in a similar situation and currently selling on eBay and running a side business. Been at it ~6 months and make 200-400/mo on top of my salary, but looking to ramp up the business more this year.
Edit: One option I overlooked of course is investing. The safer the investment, the more up-front capital you'll need and nothing is truly 100% safe. Gamble on options but be prepared to lose everything, if you really need something immediately.
Sounds reductive but I’ve had good success with this when looking for additional income.
Probably the easiest and most likely to work path if you are already a developer.
I make art piece wordclocks[0]. I’ve Sold a few with almost no marketing effort. My goal is to sell two per month.
Part of my marketing effort is improving visibility on Etsy and so I’ve started selling much less expensive items on Etsy too[1]. They are not so much for the revenue as for the traffic, ratings, and learning how to best use Etsy. These secondary products are all based on things I’ve designed and made for/with my young kids.
Two observations:
- I’ve really enjoyed the path of developing better processes of how to fabricate things more efficiently
- I’ve really enjoyed getting my kids involved with making. It’s fun to observe them thinking about how to make stuff and working with them to figure things out (they are 3 and 6).
By monetizing my hobby I can also write off tools I’d like to have. Note that I started pretty low cost using tools at my local makerspace[2].

I also resold earbuds/earplugs online for a years to get $1000-1500/mo. Seemed like a viable side project only taking up an hour or so every night to prepare packages, and then an extra 20 minutes to swing by the post office each morning.
Like others said, it's always a good idea to reduce your spending and try to save. You can even use that savings to occasionally fund projects without feeling too bad if something fails.
Run paid ads and make up for small margins with high volume. Try to offer your product at the lowest price among your competitors.
It may be easier to shave off $500 in monthly expenses and only need an extra $1500.
You can probably get about £200/day painting and decorating for people you know. If you're prepared to work weekends it'll get you nearly there after word gets around that you're trustworthy and polite...
You could also look at some CEFs. PIMCO would be the main one I'd consider for bonds. $PDI / $PCI / $PTY. If you would want to get into some equity CEFS you could look at $UTG.
Obviously you can consider a lot of other options if you don't mind them tossing off less income, but your post was bout generating monthly income :)
