At the lockdown last March, I contacted as many local food businesses as I could find, that didn't currently offer delivery, and offered to run their logistics for them. If they can package the food, I can collect & distribute. You can also just advertise on GumTree, Craigslist, Facebook etc. as "Man with Van" for £50-80/day. You may have more luck with that than I did, as I've only got a small van. Even just helping friends & family move furniture around can be an easy £50 - it's cheaper and easier for them than hiring a van (don't underestimate how many people are scared to drive vans). Avoid Amazon - unless you REALLY enjoy meeting unrealistic targets, being over worked, and under paid.
How about a mobile coffee van? Easy to set up and there is a demand in/near parks etc. No heavy lifting or much driving, Need to check legal requirements in your area though.
If you can build flat pack furniture, offer a full service including going to the warehouse to pick it up. Don’t forget furniture needs to be secured to the wall to avoid topple over accidents.
