Well, she accepts points so you can do one of these;
1-Transfer real money which you said you can't at the moment.
2-Open commisions and earn points by art.
3-Trade llamas for it which might take years because of the fact that one llama is usually worth one point and there might not be a trader avaliable.
4-Use services such as dAhub to earn points by giving llama and favouriting the person wanted which I think is not worth it.

 So my advice is that either collect real life money to get points or collect points in the site itshelf. It might take a long time but it will be worth it when you commission the ones that you admire. Sorry for my bad english :'D
