First, expand your scope of starting locations. Definately IAD, probably BWI, outer possibles might include RIC or PHL.
Second, with no indication of what airline, and what status and such, there's not much anyone can say.
There is a lot of info in stickies both in this forum and that of the airline(s) that you are interested in. Spend time reading those, as otherwise it would be half useless for us to post anything as you won't even be able to understand the language without the prep work.
