Hi Armen,
Welcome to 5 Star. I don't know much about wholesaling and it may be different in terms of needing a corporate entity or business bank account.
With affiliate marketing there is no need to Inc or form an LLC. Most affiliates simply do business as John Doe. I've heard an S corp is much better than an LLC. Some affiliates Inc for legal and/or tax purposes, but my accountant recommends against it for small one person or family businesses and says it really does not offer much protection.
This thread has some good info.
Taxes, taxes, and more taxes.
However you should really talk to an accountant, then get advice from an attorney if you think you want to go that way.
