If you need money today, then there are a few options that you could try to get paid soon. There are very few jobs where you will be paid the same day but you may be able to find ways of getting money.
The thing that most people would think of is borrowing. It might be that you will be able to borrow from a friend or family member or that you can borrow money form the bank. Although some borrowing can be a great way to get some extra money quickly, many forms of borrowing are very expensive and could end up with you being in a lot of debt. It is therefore wise to use this as a last resort unless you have a method of borrowing, such as suing a credit card and repaying it before you get charged interest that will not cost you anything.
It can be best to look for ways to earn or make money rather than borrowing if you can help it. It might be that you could do some work cash in hand if you know anyone that might have something. If you have skills you could offer to small local businesses, then this could be something to investigate. Obviously you will still need to declare your income for tax purposes even if you do not have an official pay slip. You might be able to find a more permanent form of employment as well if you want to or sign up to a temping agency. These methods should help you to not only start earning money today but to have a more regular income which will help you to avoid the situation of being so desperate for money.
You might prefer to turn to the internet to look for work. There are many sites that offer freelance work in many areas and so you may be able to pick something up there. It may take longer than a day to secure a job, complete it and then get paid though. But it can be something worth looking at just in case there is something you can do more quickly or something you can note for the future. Some sites offer smaller jobs which you may get paid for more quickly and so it can be worth taking a look to see what is available.
Selling things that you own could also be a good way to quickly get some money. It might be that you know someone who might be interested in buying some of your things from you or you could take some things into a second hand shop and see if they can offer you anything. You might want to try selling things online too through social media groups or auction websites although this may take a while so you may not get the money right away.
There are many options available and it is just a case of finding one that will suit you. You should be able to find something that will allow you be able to get the money that you need. Even if the money is not in your hands today, you should be able to start earning some which you will be able to get very soon.
