Umm Air Orlando is at Orlando I would think? Its at Orlando Executive. If you do rent out of there watch out easily half an hour on the ground during the weekends.
Personally I don't know if they have a 206 or not(only been there for the pilot shop). But if you do go there they have the best stocked pilot shop that I have ever been to (I was an hour longer than I expected to get back, and I planned for the ground time in the run up area). Call them up, their website is http://www.airorlando.com/
Sure enough I just checked, they have one, its $170/hr
Oh one more thing, I was bored and went though, I don't think that you have enough total time to rent their 206 solo. I think I read that you need 500, with 20 hrs HP, 10hrs turbo, and 2 hrs in thier 206T.
It takes more than hours to do that work. It takes some practical experience and ability, and you may find that such back country work is well outside your present experience. My suggestion would be to find a job in Alaska for a year or two in a 207 before venturing over to Africa. Do you have a job offer there, yet?
I know that it`s not easy at all and I may not have the experience but it`s the only way to continue to fly. I have considered Alaska as well but unfortunately I don`t have any offer and don`t know anyone there either.
It would be a dream to go up there and work!
I appreciate your desire; it's an honorable one. The best path to doing what you want is to find work that will give you the experience to expand on your dream. Unfortunately, if you rent a 206 for a few hours, it won't help much.
Right now you need to meet the 135 VFR minimums. A variety of 135 opreators around the country do the type of work you're looking for; you could easily start in the Grand Canyon in 206's and 207's, or flying for any number of operators in Alaska. Step one is getting the minimums down, but start applying right now. Get resumes made up and start sending them out.
Determination and desire count for a lot, mot most importantly, being in the right place at the right time counts. The best way to hedge your bet is to be in every place at every time; frequent updates, lots of resumes, and an ability to show progress in your flying. Keep hounding companies, and you'll come up with what you want.
A Squared may be able to give you a few links in his neck of the woods; he's probably the most aware of what's going on up there right now, and might be able to give you an idea where to start. (I have a few suggestions, but I think most folks who have been up there would say don't bother...LAB anyone?).
