Perhaps one of the most difficult aspects of starting a new business is locating it properly. One would not place a high-end restaurant with meals starting at $50 in the poor section of town...or any town less than 1,000,000 population. It's called market analysis.
So, I have to ask, WHERE is your anticipated market for your photographs? Looking for someone with, let's say, (US) $100 to spend on a wall decoration is getting more difficult every day. Given your location as Siberia, Russia, my limited USA-thinking is that there aren't too many in Siberia with that kind of loose change. OK, considering the internet? Join the 10,000,000 out there in cyber land trying to do the same thing. How will you get them to even FIND your website?
I'm no pro. I never have charged nor will I ever charge for any pictures I've taken. I give them all away at my own expense. But I DO have a couple of failed businesses under my belt, and I know those that have tried and failed multiple times as well. Too often it's the case of poor location, understimating costs, overestimating ones' own capabilities, and too much competition. Throw in crooked and/or uncaring employees, poor bookkeeping/accounting and tax troubles to add to causes of failure as well.
I'm not saying "Don't try", but first make sure you are aware of the risks, the losses, and the heartbreak of 'going under'.
