What sort of budget are you looking at?
While, long-term, the full DVD collections are the better option, given your circumstances, if there was a way you could save up for the basic SE standard library, that might be worth considering. It is very good in its own right, and it would give you basic articulations for all the main sections of the orchestra, including solo strings and solo woodwinds.
If that is beyond your budget, as already mentioned, if woodwinds are your first priority, starting with the standard flute, oboe, clarinet, and bassoon would be worth considering. Regarding the oboe, VSL offers two, and of the two, the French oboe is regarded as the standard, traditional one. If going with the downloads, getting both the standard and extended portions of any given instrument will give you far more articulations, and enable you to better emulate a real instrument, something that is harder to do with just SE standard.
