I have done some surveying for a company in NL, contracts I had were seasonal contracts(2 or three months) or, a contract "connected" to a project. I expect that you will get a contract for a few months as well. The flying is fun and I think I know the company you are going to work for (if so, say hi to Gerald for me
) and that means you are going to see a lot of the world. Don't think they pay much though. But definately good experience.
