Can software solve the SEO dilemma?

Are profitable, top search ranks possible without the help of an experienced search engine optimisation company?
Lets consider this: can a software package or online miracle site touting testimonials and grandeur guarantees of success elevate your online presence enough to really increase sales?
Unfortunately, unless the software or miracle website were able to research your market, find hidden niches within it, author intriguing, creative, relevant and keyword laden content, house it in a framework that meshes precisely with that content, dissect and analyse your ranking competition and apply that statistical data within the aforementioned tasks (like quality SEO companies), you'll be using that money back guarantee!! This means that search engine optimisation requires that creative human component with the backing of an established, SEO / SEM organisation used to delivering ROI!
