A family moves from the UK to Galicia

Partly a post, partly a question out to the community,

I need to improve my Spanish - Castillien (spelling?) as well as learn the local Gallego.

I already speak a level of tourist spanish, but aspire to manage both family dialogue and business.  Gallego is very ingrained and a part of the area now - tv channels, government/business as well as the local community and culture (maybe it has been for ages : sorry - I learnt/heard that Franco had banned it, and since has made a comeback : quite like Welsh).

It is an appalling statement, that in being together for 10+ years, my wife and I have not managed to teach me and the kids much at all.  Hey ho.  Life priorities.

So anyway, 6 months before we move : then a period of time when I'm still mostly in the UK working.  So stages of being increasingly fluent please...

I'm starting at the moment with Duolingo on my iPhone which feels accessible and feasible to do for circa 15mins most days.  BUT it had a 'placing test' which I got mostly correct but then it said I was an utter failure and I'm stuck covering the absolute basics and I will soon lose my motivation!  Does anyone know of a better app to try or how to manage Duolingo better?

Then how about Gallego : doesn't seem to be generally an available option with the typical iphone apps.  One suggestion was to learn Portuguese to then ease the transition to Gallego later? Any thoughts out there?

I have a couple of spanish contacts in London, so I hope to use them occasionally over the next few months to develop some business/IT spanish vocab, phrases and overall fluency.
