If you have a established website try with Flippa.com and other platforms to sell your website/blog at a good price. But that is possible if you sell it quickly. Other possibility is look for a $1000 project of freelancer.com and upwork.com and complete in 3 days of period.
to make quick money... you have to sell something... your service or any product... try both... see which works faster... personally i have only my car which worth something...otherwise, i am broke.
Check out the app Let Go and start selling old shit you don't use. I sold my old guitars, old rims/tires, motorcycle helmets, spare SLR camera... I made about $1,500 in like a couple weeks. That's a good start.
I recomend you a easy an original form to earn money: Drop Shipping The basic idea behind an online drop shipping businessis that, as a small business owner, you don’t have to maintain a large inventory of products or handle any delivery to your customers. That eliminates the financial cost and risk of having a warehouse full of stuff you might not sell, and the hassle of arranging to send orders all over the country or the world. In fact, you don't have to manufacture or store any products at all. Instead, you work with a company that specializes in drop shipping. Here’s how it works: You list products for sale on your website or a platform like Amazon, eBay, or Etsy. The same hapen with houses rent and sales, offer renting like http://www.zaharadirect.com When one of your customers makes a purchase, you purchase the product from a third-party company (the drop shipper, usually a manufacturer or wholesaler) for a lower price. This process is as simple as forwarding the order from your customer, a process that can actually be completely automated. Your drop shipper then sends the product to the customer.
It's actually very achievable with a bit of some investments in the right things (products and/or services, as mentioned earlier). I have a couple of proven ways I'm willing to share in private to anyone interested.
