Aha, new information!  I didn't realize you were including forested
areas in your considerations until now.

In general I would avoid soil disturbance in forested areas (especially
subsoil ripping!  :-o  ...but also most anything that messes up your
natural forest soil/duff/fungi/etc.),

An exception might be if you have key points inside the forested area
that collect enough water moving fast enough to cause erosion, etc. on
an ongoing basis.  In that case carefully created keyline drains and/or
swales and/or brush-dam/gabion-type structures to slow and spread the
water could be worthwhile.

Less disruptive strategies include placing downed wood, windfalls,
woody debris and brush, etc. across the slope (on contour, or at a very
shallow slope a la keyline drains) to slow water flow, increase
infiltration, capture soil, leaves, etc. moving downhill, that sort of
thing.  If you've already got downed limbs and windfalls and whatnot
it's just a matter of realigning the ones that didn't fall the right
way... :-)

We might be able to point out areas for you to look for key points, but
I wouldn't claim to locate a 'working' key point without being on the
site.  "The map is not the territory" is one of my favorite quotes... 
:-)

If you can round up enough interested people you could sponsor a
keyline workshop/course.  Would be cheaper than a consultant just for
you, and would spread the ideas to more folks.  Offer your land as the
hands-on practice site - you get design work done for your site by
participants and instructor.  That's how the advanced PC Keyline/water
mgmt. course in S. Oregon this past summer was done, and it was great
(yes, I was a participant... :-).  It is a lot of work to organize,
though.
