Permanent residence - extension for 5 yrs (St. Petersburg)

Hello All,

I am looking for someone who can help me to get my permanent residence extended. I have lost already 3 weeks on that and i am running out of time.
I am happy and ready to pay for this if anyone can get real result on this - either by contact or by proffessional services.
Need to do it in Primorskiy district as i am registered there.

Thank you all and have a nice day!
