Many of your urban area agencies usually have some type of out-of-town application process in place where you complete a lot hiring process within a few days or so. But, I would recommend that you check with each agency you plan to apply with to find out if they have such a thing in place.
Personally, I would suggest that you narrow you list of departments down to something a little more reasonable and realistic. I my humble opinion, applying to an excessive number of agencies does NOT equal to bettering your chances of getting hired. This is a common misperception a lot of people have. In fact, this approach can possibly work against you for a number of reasons.
Finally, a few other expenses that must be factored in are (but not limited to):
food
hotel accomodations
transcripts and any other document expenses
Miscellaneous other fees (For example, some departments may have application fees).
BUT,...if you are independently wealthy and can afford all the flying and expenses...good luck...
