Go to http://russart.com, switch to English by clicking the flag, go to Directory and browse movies. Those that have Plot in Russian need translation. No need to translate Title or Cast. Copy plot together with movie URL, append translation, and email it (individually or in batches) to oleg@russart.com. Attach your invoice ($ total), and it will be transferred by PayPal. That's how I see the process.

As for the price, Russian translators in the US charge around $10 per page. Plots being short, I'd expect $2-3 per plot (or per character or other per page equivalent). Also, literal translation is not required here (i.e. no need to struggle with idioms), just giving a reasonable idea of what's it about is fine. That should drive the amount of work and the price down. I'm trying to figure mutually benefitial terms and looking for a long term cooperation (years). After plots, actor bios will come, followed by reviews, etc., so a leasurely pace is expected.
