If you have to pay it now, you have to take out a loan, ask for an advance on your salary or borrow money from friends or family. If it can wait, the amount will accumulate interest until you pay it back. If it's just one month out of twelve, and the other eleven you always have money left over, there's not really anything to worry about. Put the left over money aside to pay this month's expenses. Other than that, there are only two things you can do: spend less, or earn more. Sell your car, move to a smaller place, get a roommate. Cut whatever expenses you need to break even. Try for a second job, a raise, or sell something you make.
You may think these jobs are for high schoolers, but adults aren't restricted from babysitting, housesitting, and petsitting. In fact, you might be able to garner $100-per-night babysitting! I would start offering these services to friends, family members, neighbors, and colleagues, since they would probably rather hire you instead of someone that they've never met.

Then, if my piece of content is so unique and valuable around hiking backpack recommendations, that other reputable outdoor websites are willing to link to it and build the page’s authority, then I’d have a very real opportunity to rank high in organic search for these search terms (meaning, my page will come up first when someone searches for hiking backpacks).
Nielsen (the same company that creates TV show ratings) has a research division that is similar to what survey companies do, which is gather information to help companies better market themselves to customers. Instead of having you take surveys, though, their computer and mobile panel is focused on gathering information pertaining to your “unique internet usage with people like you to build a picture of internet behavior.”
People are always looking to have their cars washed and detailed. You could be a mobile car washer and detailer without having a permanent location. Reach out to people you know or make some flyers and put it in your neighbors' mailboxes. If you want to get serious about it, prop up a one-page website or give out business cards. You can make money quickly doing this.
