You can get a 3 month multiple entry tourist visa pretty easily. It cost's about $140 for the various fees. You have to google visa agencies and fill the form online. Sometimes you can get 6 month visas also though I can't seem them on line at the moment. When it runs out you can fly to Singapore or similar and apply for another. The Vietnamese don't seem to worry too much what you do once you are there. I'm probably off there soon to hang out in Saigon which is quite fun but more expensive.
Yes Saigon is quite a bit more expensive than where I live. But there is a lot more going on there too.
Regarding visas - the parent is correct. I would only add that you can also make border runs to Cambodia from Saigon - which is a few hour bus ride and quite a bit less expensive than flying some where (around $10).
No worries. A few years is a bit of a commitment but it's a fun area to travel / do some coding for a few months. Chiang Mai is also popular with startup types and not that far. I liked it there and Angkor also was kinda fun.
