I would definitely not recommend starting a new business on borrowed money, unless you are very experienced in the industry you will start the new business, have lots of associates who have already committed to purchasing your products or services in large quantities and have already paid a sufficiently large amount in total to cover at least 50% of your start-up costs.
(Actually, if you are in that position, you probably wouldn't be asking here for a source of money.)
Other than that, it would be foolhardy to start a small business on borrowed money. I wouldn't even recommend borrowing from friends and family unles your own money is more than 50% of total funds.
If you cannot start on your own, partner with someone you already know and trust who has the money and work the new business as a partnership. Failing that, go get a job, save hard and organize yourself towards starting your new business with your own money.
I wish you well.
