1. Hosting, I suggest lunarpages.com they are reliable and you'll hosting for your website. I don't suggest free hosting as you are trying to sale something.

2. Use an opensource program, they aren't that hard to install and they all have support forums and many will install for free, I'll do it for you contact me. Joomla is the best in my opinion, it's free with free templates that you can edit to suit your needs then later if you do well, have one custom designed.

3. Other useful opensource programs: Wordpress for you blog, PHPBB for your forum, and osCommerce for your ecommerce website. Just type in the names and you'll find them on the engines.

4. If you prefer straight HTML templates then oswd.org provides free HTML templates, you'll need an HTML editor search for free ones on hotscripts.com

any other questions let me know.
