Russian speaking community in Doha

Hi, everyone!
I would like to ask a few questions to ex-USSR expats in Doha.
Is there a big community of Russian-speaking people? Is it an active friendly community with internal communications or people just live their own lives?

And I don't actually know where to find the general info about living in Doha, so I'd like to figure out, is it hard to find job for the citizen of Ukraine and to obtain a work permit (or working visa...)?

And what are the average rent price for a good 2-bedroom appartment?

Thanks in advance for tha answers...
