If you decide to breed, be sure to have enough space and a plan about what to do with excess rabbits beforehand. Any of the kits I can't keep or sell go to Camp Kenmore. I too don't breed my does more than once or twice (quite often they manage a second litter without asking me about it) a year.
Breeding for wool sure is interesting, but I guess not the most easy way to get into the hobby. But if this is your goal, you have the time and resources, and already a use for the wool (I have a nice pile of tanned pelts, and no real use, all I made til now is a winter cap), read up and go for it. Have a plan B ready to abort the experiment if it doesn't turn out to be your shtick, like returning the rabbits to where you got them from - just don't make them other people problems.
Don't even think about making a profit, isn't going to happen, much more lkely a rather complex endeavour like breeding for fiber is going to be a money pit.
Breeding rabbits isn't rocket science, just one or two generations ago they were a very common staple food around here, even now we are 3 breeders in my rather short alley. Since I'm alone one of the biggest downsides for me is that they need to be cared for twice a day, no matter what, takes me about 20-30 minutes each. So, if you leave home you'll need someone.
