Instead of taking out a loan for your start up when the capital is not sufficient it is better to try crowd funding. This is the style of inviting investors to join as a financier of your business. In return they will get a portion of the ownership just like a corporation. But the certificate of ownership is not formal since your business is just a single proprietorship. The usual people who will accept your crowd funding request are those in your family, relatives and close friends. You can also try your colleagues in school and in the office if they would like to support you.
