@katheryn There are many sites where you can find lenders willing to provide such loans. The most common way of getting this type of loan is through online services that work with people that want to borrow, rather than those who offer these loans themselves.
Developing countries, such as the United States and many markets in Asia, often feature microfinance services that offer small loans in exchange for good-quality collateral.
You can borrow from friends or family, but they may not offer the interest rate flexibility or the service you need. You can also get a direct cash loan from a lender, but these sources are typically very expensive and don't usually provide the interest rates you want. Additionally, your local bank may offer a personal loan, but they typically don't offer very competitive rates.
Many banks offer small loans to small businesses. Banks are normally funded by money deposits from individuals and other financial institutions (such as insurance companies). Banks may also be backed by governments or different institutions collecting taxes or purchasing goods and services.
You can also get a loan using peer-to-peer lending. This kind of financing involves you giving out the loan to another person and that individual repaying it to you on set chunks of time. The lenders could be other individuals or companies who may choose to invest in loans that they believe have the highest rate of return.
