If anyone is ever interested in how to obtain a Private Visa this is how I obtained mine. I would assume it is the same for anywhere in Russia. I obtained a Private Visa because I stay with my fiancée and in January 2009 on my visit I had a tourist visa. Not really knowing the full details, and not realizing I should have registered it differently

, we went to OVIR and were chastised for me having the wrong type of visa. They told L if it happened again they would fine her. Maybe in a city other than Izhevsk there might have been other problems, I don't know.
I scanned my bio page from my passport and sent her this in a pdf file. I could have sent a jpg file just as easily. L went to OVIR and she had to complete the following questions:
1. Country of birth.
2. The exact place of birth (City, State).
3. Where would I obtain the visa: Country, City, where there is a consulate of Russia.
4. Place of work: the full name of the organization (firm).
5. Position at work – job title.
6. Employer's address (full address of the organization, company)
7. Type of work of company.
8. Cities to visit in Russia.
She knew these answers but did not know how to give the answers in Russian. She had to have her English teacher help her.
It took three weeks for her to obtain the visa. She sent it about a week later by Global Express and I received it in about 6 days. Sent to SF and used normal 6 day processing - no need for a rush. Had my passport back with visa 13 days later. Figure 2 months, less or more depending how sent from Russia and the processing speed. Company I use in SF cost me $160 - I receive $10 off each time after the first time. They also send me coupons I can give to others to receive $15 off. I paid UPS ground (next day for me because of my proximity to SF) both ways which cost less than $10 total.
The cost for her to obtain the Visa is minimal. Even with her sending it like she did I feel it costs less than paying someone additional for the tourist invitation AND paying someone to register it for you. But, it is obviously not as quick.
I'll black out some sections and post a photo in a few days to show you what the Private invitation I sent with my visa application looks like.
