Investment Manager / Finance work for Expat


I will be moving from the UK to Buenos Aires at the end of this year and so this is the first of probably many posts!
Although will continue to earn British Pounds from UK financial consultancy work, I am very interested in the possibility of working full or part-time in BA, for a company or individual(s).
I understand there is a growing number of financial companies outsourcing work to companies in BA (from Europe and the US for example).
Can anybody offer me any help here, or in general terms regarding job opportunities in BA.
Many thanks
