[i]traditional [/i]music theory, in terms of examinations, tends to be just as concerned classical history and knowledge (ie when did Beethoven last wash his socks?).
It seems to be the application of theoretical knowledge you are after? I'd recommend teacher who knows his stuff, and can show you in an easy to understand manner how to use the modes, work with harmonies etc.
Probably a bit more of an expensive option, but some tutors are happy to see students monthly.
