As you start regularly putting out content, you’ll hopefully start to build a bit of an audience. But to start seeing real money from YouTube you need to market your videos elsewhere. Share your channel on Twitter and Facebook. Distribute videos anywhere else you can think of. Also, interact with comments and build a community around the videos you’re making so people will share it with their friends.
I see a comment made by Stella including some freelance sites. This does work. I use oDesk and it’s been a big help in bringing in a little extra money. I also agree with some of the other comments that mention people should think of or view more ideas of making extra money, because it really is possible to make extra money instead of just sitting around moping about not having money to pay the bills or buy something special.
eBay: With eBay, the procedure is very similar. You simply start by becoming an eBay seller and stay in good standing by making sure your PayPal account is verified, and then you can sign up for your store. These three steps allow you to piggyback on eBay’s reputation, reach, and sales and marketing infrastructure in order to sell your own products.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
While writing also falls under the category of an actual work at home job, it can be great for extra cash, too. Particularly content sites. These are sites that post writing assignments for any of their approved writers to grab, and for most you only need average writing skill to become an approved writer. While the pay isn't fantastic, if you can write fast, you can for sure earn substantial extra money. Most of these sites will pay a penny per word or more:

Robert said he did an average of 4-6 of these gigs per year for a while depending on his schedule and the work involved. The best part is, he charged a flat rate that usually worked out to around $100 per hour. And remember, this was pay he was earning to advise people on the best ways to use social media tools like Facebook and Pinterest to grow their brands.
