If you are looking at making money on the Internet seriously consider investing in a professional website. No matter how great your product is it will not sell if you don't take the time to build up the platform.
- Market research - analyze your keywords, industry, competition, customers, Revenue streams, etc
- Professional design that leads customers through the sales process
- Cutting edge programming features such as video, rss news feeds, forums, customization, etc.
Redesigning a website can increase conversion rates through the roof... after everything is tested then spend your money on adertising, otherwise it could be wasted
