Some question about finish basement

[doublesky]

I have some basic questions about finish my basement.

My house is 4 bedrooms single house. I want to finish my basement.

1. For basic finish, how much will it cost to let somebody do it?
2. How long will it take to finish the whole basement? If I want enjoy the basement during this winter, for example in November this year, when should I start? Should I put order now?
3. Any good company to suggest?

Thanks a lot.
