I have never requested a police certificate from a Russian consulate, but I have dealt with one many times. Here is the information provided by the Russian consulate in San Francisco concerning this exact issue:
"To request documents from Russian archives, it is necessary to fill out two copies of the application on each document and to attach $50 money order (addressed to the Russian Consulate) for each requested document that does not exceed more than five pages (if it does – plus $15 for each additional page).
To request information about the absence of convictions in Russia, please fill out the application and enclose a money order of $50 (if Russian citizen) and $110 (if foreign citizen)."
http://www.consulrussia.org/Protocol/main_eng.htmIt does not say how long this process will take but a hint is given at a different portion of the website:
"You can send a special request for confirmation of the absence of Russian citizenship to the Russian authorities through the Consulate. It takes time (approximately 1-6 month), so, please apply in advance."

However, the cost should be a lot less than the fees that are charged in the US. Russian authorities must think we USCs grow money on trees. So look into the cost and wait time, as it might turn out that it will be cheaper for you to either make two trips or one long out to Russia yourself, or have someone on your behalf get the police certificate. There is some kind of power of attorney document you can put together for this as well, but I do not know the details, but the Russian authorities at the consulate and especially at the police center will know.
