I just have to ask this because I have been running online businesses since early 1996.
What is the installation? What is installed?
More importantly why does the installation cost so much? That price tag is a deal killer for 99.99% of the market. Pricing for intangible stuff like this is an area of endless fascination for me, that's why I'm curious. Why not offer a free installation and only charge a monthly subscription fee?
With the Net you want to go for scalability. You kill off any hopes of benefiting from scalability with this pricing structure.
