Are you saying you want to go from engineering to accounting .... ? How long do you want to study for your new career? Also, why on Earth accounting, and why specifically in that field?
I don't work in that area but know a few accountants, and also some civ engineers who have worked in that area... I imagine you are planning to work in the field or something? (ie on location in a remote area or something).
Good luck. It's a long shot trying to network on here for something so specific, you should network everywhere else you can, there might even be some kind of bulletin board for accountants in that field. But good luck and good on you for trying, nothing worse that a job you hate, and a job you don't really love, that's the next worst thing.
