barrysloateI would try to retain the original covers if you could. I'd rather have an original book with some condition problems than one with the covers replaced.
You probably don't need major work if you just want to reinforce the hinges, but I don't know anybody who could do it reasonably. I have a paper restorer but I've never asked him to repair a binding.
I guess I didn't really answer your question. Maybe you can google something and find someone who can do the work. The books you have are not too expensive, so if you can't get it done cheaply it might be better to just sell your copy and look for an upgrade.
