How much time it takes partly depends on your set up, and partly on what you intend to do with your animals. If you are raising rabbits to slaughter, you may not care that they aren't particularly friendly. If the kits are meant to be pets, it's important that they get lots of handling so that they are people-oriented, and that takes time.
I don't know about Georgia, but some states do have laws in place regarding the age kits must be before you can sell them, that sort of thing. Depending on how many kits you produce and who you sell them to, you may need to obtain a license. I know of one person who had to get rid of the dozen or so rabbits that she was keeping in a garden shed because her HOA had a cow over them, so checking on local regulations is a good idea, too.
And of course, there is always the problem of what do you do with the rabbits that for whatever reason don't sell.
