I "sell" IT contractors, including developers. My advice - get yourself into "Agile" methods, Extreme Programming, Scrum, DSDM, Lean - that sort of thing, and hone your Java and/or .net skills to deliver high quality test-driven code.
No forward thinking company is interested in SSADSM and even Prince2 seems to have had its day or perhaps there are just already too-many Prince2 Practioners around already - go Agile. The great thing is that it works (when done properly).
