Depending on what's around you and what your skills are, here's some random ideas for quick money. Some may involve more networking than others.
Dog walking, errand running, house sitting, pet sitting, baby sitting, house cleaning, yard work, donating plasma, participating in medical or psychology experiments, tutoring, skilled freelance jobs (painting, writing, graphic design, photography, carpentry, etc).
I'm sure there are plenty others as well. Probably a bunch of legit websites online where, if you had the time and energy, you could make some money doing surveys, reviews, etc. A friend of mine became a mystery shopper and it paid well for her.
