Saint Petersburg to Magadan

I am a photographer and videographer driving my Land Rover Defender from Saint Petersburg to Magadan (via Yakutsk). Leaving around 5 September and will take approximately 1 month. There is another friend joining me but I want a Russian photography student/ freelancer who is looking for experience in adventure travel photography. No hotels, comfortable accommodation, all camping and 4wd roads. Must be prepared to rough it!
