n00b questions about protecting your identity

Hi guys,
thanks for having me as a member!

This is my first post. I've done a few searches and couldn't quite find any posts related to my question, so I though I'd post a new thread.

I've been interested in IM for quite a while, and while I've got some great ideas for products and have read up quite a bit about it, there's a few technical questions about protecting my identity and setting up company names I'm concerned with.

At the moment I'm currently in a full time job, and while I guess it might seem like I'm predicting more success than I should expect, what are the steps I should take to keep my name and other personal details private?

I'd like to have a business name on paypal, but as I've no track record and no actual real business, do I need to set up a business/company or trading name before I can apply? I currently reside in Australia.

Can I change my name or have multiple accounts on Clickbank?

The reason I ask is that the ideas for products I have are in different fields, and I think it would affect sales if they are all going through the same name for my products which I think would seem quite unrelated to the products I'm selling.

I realise that there are people on this forum that insist I should use my own name for anything I'm doing, but as I said, I'm still in a full time job, and until I can prove to myself and my family that this is a valid form of income, I'd rather remain as anonymous as possible, even if I might end up making less money or having less credibility doing so. The rich jerk can protect his real identity, how can I as well?

I've looked at clickbank and paypal, but I seem to be going around in circles, so I thought I'd ask the experts on this forum.

Thanks in advance for any responses.

Brock
