LLC and asset protection

[Isaac A.]

I need assistance with this. I have not done any deals. I want to start very soon, but I don't want my name to appear on any deals; I am thinking of forming an LLC to do purchases. How much does it cost? where do I form it?- Nevada, Delaware, Wyoming....?What are the tax advantages? Will I pay more taxes? Will my name be completely hidden from all transactions? Should I get a P.O. box in order to hide my home address. Should I open a business account first? Can I do this on my own without hiring someone to do it? Will I be able to qualify for loans? Lastly, by forming LLC, will I be considered as self-employed? Any information is helpful. I am not sure about reliability of internet resources.
