Job Possibilites in Sri Lanka (Colombo)

I am a foreigner, my husband is Sri Lankan. Will be returning to Sri Lanka and wanted to know how to find small job in Sri Lanka. I would need it to be close to Moratuwa and prefer not much further from Mount Lavinia area. Anyone know any employers who hire non-sri lankan? And also, how to get permission to work?I assume embassy gives the okay, or does employer wanting to hire foreigner assist in obtaining permission to work? Thanks all in advance :-) Parissem inna
