If you have a car, and it's insured, you might be able to cut back on premiums you have to pay by moving the car to a "storage" status. It's still covered for theft and things like that - just not "moving" type problems like collision and liability. And then go places on a bicycle or using pubic transportation or have friends drive you.
Cut any entertainment budget to bare minimum. You can often times put things like cable or gym memberships into a "vacation" status and save some cash that way rather than outright canceling things that you know you'll need later, after the cash crunch has ended. Libraries are a great place for any entertainment needs. You probably have free access to physical books, eBooks, audiobooks and DVD's.
I mow my own yard (actually, the wife does usually, because she says she really likes doing it - what a strange woman!) but if a neighbor came and asked if I wanted them to mow my lawn I would certainly pay them well to do it whenever they wanted to, realizing something must be up.
If the money need will be longer term, a roommate to share living expenses might work out if you can find the right person.
Even though we are lucky enough to be able to eat out any time we want to or buy whatever we want in the grocery store, we seldom eat out and I choose the meals I will fix based on what I find on sale in the grocery. I walk into the meat department and if chicken is on sale, well, that's what I'm having for dinner. A few days later it may be salmon that's on sale. Then the hamburger will be on sale. The stuff the meat department puts on sale is the stuff I normally eat. So it's not like I'm compromising on quality or anything. I'm just letting the store choose when I'll have any given meat based on their sales. They rotate their sales, so I get lots of variety. Onions are always cheap and stretch out meats nicely. The other day I sliced up and sauteed an onion, then mixed in a pound of hamburger and browned the mixture with some added seasoning (random stuff I pulled out of my cabinet). You won't believe how good that simple dish turned out, and it gave us lots of leftovers for more dinners. Veges are always cheaper than meats, and slicing up a tomato makes a really good side dish IMHO - just tomato slices and a little salt, nothing fancy. Or if avocados were on sale, slice up one of those as a side. Nothing says you can't have a small meat portion and then four side dishes if you want. That may not be the restaurant standard of presentation, but it works. Be creative and observant in the grocery and you can save a ton of money. Stay away from heavily processed and prepared foods - both for your health and for your wallet. Food makes up a larger portion of your budget than most people realize. Stick with the basics from the produce and meat sections and you're usually in much better financial (and health) shape than the canned, packaged and frozen stuff.
