Have the same problem, in the business centre services are provided by Beeline. And the prices he has for legal entities — just space, we have for example the cost of the Internet is equal to the cost of renting space :-)
So I sit on the Yota, well, Yety there are routers.
Comstar WiMax runs much better, but the inability to share, unfortunately, so we don't use.
There is a business center where Internet included in the rent, but the rent accordingly significantly higher.
