My biggest problem in starting my own business is finding wholesellers. It seems that it is difficult to find them online (or is it?). For example, I would like to start an apparel retail store online. Where do I start to find wholesellers? I really need help! Any input will be helpful. Thank you!

If you know any other ways to find other products (it doesn't have to be apparels), based on your experience, please input as well. Also, did you need a business license or seller's permit to gain access into these wholesellers? Starting off, I don't want to purchase all that yet since I have limited capital.

Thank you.
