If you need money really quickly then there are a few things that you can try. It can be tempting to go straight for the borrowing option. While a loan is a solution it may not be a very good one. You will have to repay the money and also pay fees for the loan. These can be pretty expensive and you might end up being worse off once the loan is repaid. It is therefore better to try to earn some extra money rather than borrowing it.
To start with it can be worth asking your employer if they can give you an advance on your salary. This means they will give you some of your pay early. This can be really useful. If this si not possible then you will need to think of a way to get more money. Selling things that you own but no longer need could be a way to do this. This can allow you to get rid of items that you no longer need and also to make some money from them. How much you can get will depend on what sort of items you have and how valuable they are seen as being. You can sell in different places depending on the item, perhaps an auction for more valuable things, a local social media page for heavy items that you cannot post and a car boot sale for cheaper, smaller items. If you price things at a really low price then you should be able to sell quite a bit and make a decent amount of money.
If you have nothing to sell then you will need to think of another way to make some money. You will need to earn money form finding some work to do. This could be best done by finding some temp work in your local area. If you go into a job agency they should be able to offer you some work and even if it is just for a few days it should be able to give you enough money to help you out. You might even be able to look at agencies online and see what sort of vacancies they have. You will often have to be available very quickly, to fill in for some one that has called in sick or something like that, but it can be worth it.
Some people do have some success with finding online work. There are different types of work available to do and so you may rather do this. There are many places online where you can look for work and so you should be able to find something there to do. It is worth bearing in mind though that online pay can be quite low and you may have to earn a certain amount before you will get paid. So check the terms on the sites you are on and make sure that you are happy with them all before you start doing any work.
