I'm Indian, work in Moscow, can I get a 12 months multiple enry visa?

I am Indian national working here in Moscow. I have my garment business in India and travel at least 4-5 a year to China and I never had a problem while applying for a visa in India. I normally live there for a week with my friend in Guangzhou and register myself every time in the local register office in Guangzhou. In fact I have a copy of my last registration in Feb 2011 and have at least 5 China single/double entry visa stamps on my current passport and an equal amount of stamps on my expired passport.

My question, since this is my personal business trip do I need any documents from my current company that I work for in Moscow or can I apply for the 12 month multiple visa based on my own credentials? Also do I need to show a return ticket as my schedule changes all the time? My next trip is scheduled in August 2011, I will first going to India for 1-2 days & then flying to China. Since I live in Goa it would be very difficult for me to go from Goa to Mumbai to apply for my visa, I would lose almost a week if I do so. Please suggest?

Thanks,
Pele
