Web Help

I am starting a new project. I want to have a web site that goes along with the project. I want to know if any of my friends can give me any advice about this.

1) What hosting company?

2) Is it hard to have a Wiki site?

3) Are there any easy mapping tools out there?

I want everyone to remember I have no web or programing skills. I am looking for help or advice an idiot could carry out.

Thanks
