Best bet is definitely to go with your bank, but 99% of banks probably aren't going to lend you a pile of money for some "internet business".
If you're looking to get a decent sized loan, I'd recommend looking into setting yourself up as a business first, making a business plan, let a few months go by, and go to your bank with a balance sheet.
The bank wants me to borrow more of their money today but when I started out they weren't even willing to give me 5k without me providing collateral.
