Hi
Esocarras1 and welcome to the GPWA.
First off I should point out that I'm not based in the US, so I can't be specific about the exact procedures but here are a few pointers on affiliating.
1) There are lots of US based affiliates who promote many things from Forex, to gambling, to books and lots of different stuff in-between.
Nothing in the UIGEA says that being an affiliate is illegal, mind you if you've been reading this site and the APCW then you'll also be aware that nothing in the UIGEA actually says playing poker is illegal - but that has not stopped the US Government issuing mis-communications saying that it is.
The big issue seems to be about perceived loss of revenue, and missing tax revenues - rather than gabling itself - as land based gaming is still encouraged.
2) However, if you are promoting gambling specificially, then given the somewhat hazy US stance on all things gambling it's probably better to describe your business as "internet marketting" or "internet promotions" when discussing things with the bank and uncle sam.
It's all true - you're just not specifically mentioning the product.
3) A lot of affiliates start off without incorporating a company - create a website, get a few products on, build up links and traffic etc. Just keep a record of income and expense and make sure that you're squeaky clean on your taxes.
4) After the first year or so, we can hope that you are seeing a regular profit stream every month, and then it's probably time to worry about creating a local company to cover all your activities.
Again I'd just stick to a generic lable like advertising, promotions, or even internet consultancy to describe what you do - the more generic the better.
hope that helps mate.
