Argent, you may get some decent binding with a tight sportsbra (the frog bra could work for you) and then a binder over top. You could also try two sports bras to start, one a size smaller than the other. My DD's aren't flat in a binder; I look like I have the pecs of a 200 lb man, but they're pretty unnoticeable if I dress to hide them.
Sports bras are easy to find, much more comfortable than binders and relatively cheap; I'd start there. Good luck!
If I get a chance I'll post a few pictures of my chest in various stages. It was something I could have used awhile ago and really didn't find much of.
