While the points here are interesting, other approaches can work just as well and save money by eliminating, or modifying some of the steps.

Instead of gathering tons of peripheral support, work in a linear fashion on your own. Use webhosts that provide templates, if you feel the need to have a website. Some affiliate programs, like the Amazon Associate program, allow the creation of a storefront that remains on their server. Using links to the freestanding storefront eliminated 3/4 of the time and expense of having other people involved in site building and maintenance.
