How to Obtain a Business Line Of Credit

Hi, I am looking into obtaining a business line of credit, but I have one major problem --I have no business, LOL.

How can I obtain this type of line of credit and what business should I apply for? I’m an engineer, that has indepth knowledge of computers, programming, and IT infrastructure. Also, Website development. Could you recommend a business so I could qualify for this type of loan. Thanks.
