Next to my main contract I have some stuff on the internet generating some regular revenue via Adsense.
I can’t renegotiate my contract at the moment, and I can probably maneuver my Adsense stuff a bit to make it more efficient.
Are there some other ways I could use my skill set that could help me improve my financial situation? Given the short time frame I’m looking for things that I can do with my skill set but don’t require a long time to spin up, and ideally generate significant returns.
Any suggestions?
This will cost you the taxes, so up to you if it's worth it.
I'm not sure that's a wise choice.
As for your skills, we would need to know what they are to even have a clue what you could do with them...
Advertising (especially programmatic advertising) isn't having a good year.
Ask the existing client for referrals if you can.
Set up a landing page at Carrd or Github Pages or wherever with your experience/skills if you don't already have a website. Make sure your LinkedIn is up to date.
Reach out to digital agencies and software shops for overflow work. They always need help. It's not great for building your name and isn't terribly lucrative but you can definitely drum up projects fairly quickly. And they will be repeat clients since they have a client roster to tap into.
Almost every tech these days has a Slack or Discord with an informal job board. Monitor and respond.
Reach out to established freelancers. The good ones are busy and get more leads than they can service.
Upwork isn't terrible if you target the high end and pick a specialty. Do not try to compete on price or list yourself as a jack of all trades.
Reach out to recruiters and let them know you're looking for additional contracts.

Good luck!
