You need to sit down with a competent software architect and go over what you want with her/him. You need to tell them what you want to accomplish in pure business terms and what monetary resources you have. It will be the job of this software architect to plan out for you what needs to be done technologically to achieve what you want.

In an ideal world, the business side should not be dictating what technology to use. The world of technology is too vast for someone who does not know the various ways to build a website to learn in a day and decide for the technology group.

Update: I disagree with the posters who say "technology" is a buzzword. A buzzword is a word that is fashionable for a period of time, a fad. "Technology", the word, will never go out of fashion. The buzzwords are the children of "Technology".
