You can try applying
through online or better yet apply in person when you are in Laos
since many individuals and places still do not have or use the internet
as often as the rest of us do.
One suggestion
I've heard is to become a volunteer. Usually after then, the organization
you were working for will be more likely to hire you on to paid staff.
If you're an expat
looking to work in Laos you're company should be able to help you
out with a type of extended (work) visa.
Even if you do
find work in Laos the pay may not be as much as other more developed
Asian countries. But if this is no concern to you and rather you're
interested in being in the country, learning about the culture/language,
etc. then definitely working in Laos will be extra fun for you.
