How to advertise an academic job in a small Asian country to US/European candidates? I am a mathematician, recently returned home to Malaysia after a decade or so in the United States.

I had experienced for myself the pain of the US academic job search in snagging my postdoc. Now I am on the "other side", so to speak. My institution, Xiamen University Malaysia, is brand new and growing fast, so we need to hire a lot of mathematicians.

From my time in the States, I know there are many brilliant, hard-working people with excellent research records who cannot get permanent academic positions in the west due to the scarcity of jobs. I think my institution would provide an excellent opportunity for them. Obviously we cannot offer the same financial package a western university can, and I'm sure it is difficult for a lot of job candidates to consider a move across the world, but it is reasonable for the cost of living, and we teach in English and offer a teaching load that is conducive to research. I think it would be reasonable for a western-based job candidate to at least consider us. 

My question is, how do we get the word out in the west? The obvious solution is Mathjobs.org for the US, but we don't have the budget for advertising there. I have emailed hundreds of department heads in the US and Europe, but I doubt many of those emails got forwarded.  Are there any other avenues to try?
Try conferences. I'm not in math but in my field most of the job news comes via conferences and academic societies.

It helps if the jobs are for specific subfields, so you can advertise them to the smaller conferences/societies for those subfields.

You may also try focusing on conferences/societies outside of the US, like Australia, NZ, Canada (e.g. Canadian Mathematical Society). Jobs in smaller countries like Canada are harder to come by and people on the market might appreciate seeing other non-US options.
