Ditto. Also, look at the breeders section to see if any members have anything you want. I would also buy from tortoisesupply.com Tyler, the owner is a member.
Rescuing a tortoise, then bringing it into a WORSE place isn't rescuing at all. Rescuing isn't for a person new to tortoises. This is because most rescues have illnesses that are more difficult to care for.
Google works too. But every subspecies is different.
Did you read this? http://www.tortoiseforum.org/thread-63799.html
This will explain EVERYTHING. In order to be a good pet owner, you're going to have to do some research.
I suggest you look in the pinned topics at the top of the Russian section and read about the care. Then if you have any questions afterwards, everyone would be glad to help.
You could look up on google, bing, etc. whichever tortoises you are interested, and find all of the information you have been requesting here. You can find care for them by simply typing "Hermann's tortoise care" in a search engine or here on the forum.
I would be more open to new tort owners taking on a rescue. As long as they do the research and recognize the responsibilities that they are taking on. Otherwise you are promoting breeders that sell to people that don't understand what they are taking on. Not all breeders.
Dont get me wrong, Rescuing is fantastic, I am a little rescue myself, but I dont advise people to go and grab a sick tortoise as their first (tort) pet.
