Once in Beijing track down the Beijing Tiyu Daxue(not hard its huge),this is the official psyhical training uni,and has all the stardardised MA plus sanda.You well be able to get contacts there who will lead you to the countless other schools/styles (traditional and modern)who will be happy to teach overseas people.From there its up to you.
Its all about guanxi.
Have fun
