Domains, hosting, websites, layouts..., etc and so forth Options

[ChasingLife87]

Yes, I searched.

I've been hosted at ka-boink.net and am now hosted at ill-wed.com (heather ), but I really feel like I would do better with my own domain. So here are my questions.

1. Google is being vague. And the big book of resources doesn't seem to have what I'm looking for. Maybe I skipped something. But what is the basic price range for the domain name registration, and then the hosting?
2. Do you get them separately or can you get them together?
3. How long do you keep your site? Forever? Or do they expire? (ka-boink.net, where I was hosted originally, expired, and that's why I ask.)

My other questions. I am really thinking about a side job selling website layouts, much like talented designers such as Heather and Roxy do.

4. How exactly do you advertise that you are selling?
5. Do you have to use paypal, or what?
6. What kinds of scripting languages do you NEED to know before people take you as credible?
7. What kinds of layouts do you consider sell-worthy and what kinds don't you?

Sorry to bug you with a million bazillion questions, but I'm hugely interested in this and am hoping that one of you experienced members can help me out.

Thanks!
