Simple Questions

[tte]

I have a question. If I want an OFFSHORE E-SHOP. What exactly do I need. I know I need A DOMAIN, and OFFSHORE WEBHOSTING. Then I need to GET FREE SOFTWARE or SOFTWARE to set the shop up. Does this sound about right? Can anyone elaborate on the steps I just named. Thank you in advanced. There is so many things out their I read and all it does is confuse me. So if anyone can clear this up thank you.
