Inga, don't expect to rent anything in Reyneh. You might find some water there, but that's about it as far as I know. Also, bring plenty of fuel, as you won't find any source of water on the mountain at this time of the year, except for snow.
I'm pretty sure you'll need crampons too. I climbed it at the end of september (end of summer) and there still was plenty of snow. The way down is long enough to pack them. Good luck!
