I made the Woodland Caribou trip a few years ago, and wrote an article in the BWJ about it.  I highly recommend Albert Rogalinski out of Red Lake as an outfitter who will help with route planning and any options for transport into the park from Red Lake (we flew...a wonderful and not so expensive option, again, arranged by Albert.)

Woodland Caribou will give you a true sense of wilderness.  Portages are sketchy and hard to find, campsites are sometimes not where they're supposed to be.  We bushwacked a few campsites after giving up on trying to find the ones marked.  It's an amazing place.  Not for everyone.  Some might freak by the notion of being ALONE.  We never saw a person or canoe in 9 days.  By the way, if possible, I'd give yourself more time...

Gulls haven't even figured out that canoes generally mean a free meal of fish guts....the fact that they weren't habituated told me a lot about the few people who go there.

It's an unregulated park, so you have to be careful on trip planning if you don't want to see power boats and cabins.  But it's doable.  When we went, floatplanes could go anywhere...I think they're a bit more restricted now.  

It's a fantastic place. Fishing is ridiculuous.  Actually too easy.  

I'm going back next year.  Have fun.
