I guess it's just as hard as anywhere else (meaning hard as hell!).
I've been making part of my income from professional photography for about 13 years in Montreal and I can assure you it's not easy. I'd say about 90% of the job is PR, promotion and stuff like that. You have to know the right people to get some decent opportunities. It's all about who you know. There are so many photographers around it's ridiculous.
Personally, as soon as I find something else that's steady enough, I'll quit pro photo completely. I'll just do it artistically, for my own pleasure. Ironically, I might end up having a lot more success that way! I have one artistic project that's coming to life slowly. Haven't shot a single frame yet and I'm getting offers for gallery space, publication and other stuff. Finding regular crappy and boring normal work remains hard though.
So, Yuri, if you're really good at doing your own PR and are extremely aggressive in the market, you might have a chance. It's an uphill battle though.
