Agile Business on the Web (long)

[Mr. Now]

Those are interesting ideas. If an existing site's traffic can be leveraged to jumpstart a closely related idea, and/or if the site has robust SEO on essential keywords, and solid PageRank, $5000 can be quick and cheap.

For example it costs 100s of hours to develop good SEO on competitive search terms, and you have to let it mature over time, at least 4 months.

There are pros and cons to both sides of the buy.vs.build aspects. For example, the code under the site can be unmaintainable-- and often is.
