I think construction.. people will always need someone to build their houses/shops/buildings. Nepal lacks a good construction company, which has dependable workers (who won't disappear from work as when they like). There should be a sole company that consolidates construction worker groups such as tekhdars, bijauli wala, marble wala, everyone. See what I mean? Instead of having to take on the unnecessary burden of looking for good ones yourself, you can just call up a company. Tada! Done. How's my idea! Lol.
