They have a few other suggestions here:

but nothing exciting/earth shattering.

I assume you have a pretty tight but good budget/know how much you spend each month? I think I would try to think of 4-10 people I could approach who might be able to outright give me $20+ a month. Maybe I'd make it 20 + dinner out at the place of their choice where they pay for dinner and hand me a $20 :-) If I could, I'd think of situations where I could perhaps "pay them" back in services, like cooking, cleaning, dog walking, watering plants/gardening, house sitting while they're on vacation, babysitting, etc. I'd keep it informal so it was just a small nothing gift but which would net me $100 or two more a month.
