I like Smith's idea, the one thing I might add is if there is a local you feel comfortable with and they have a day off when you want to go, ask if they want to go with you as a guide, and pay them for their time, their fares and meals on your adventure. If there is a local taxi driver you are comfortable with he could do the same, it will just cost a little more for tying up his vehicle for a few hours. Work out the details and agree on costs before you confirm the plan.
