If you "just want to give [yourself] the best possible chance for success with [your] situation," you'll go to whatever time/expense/travel necessary to get with a good, professionally-trained teacher.  If you can't get to him/her every week, do whatever schedule is practicable.  But otherwise, really any "skill" you might manage to acquire on your own will eventually need to be torn down and re-done with a teacher anyway, assuming you don't quit first.  Which, if you try the DIY route, is the most likely outcome.  I give this cold assessment based on long experience and because all of us here would like to see you prosper and succeed on the instrument.
