If you get a kit you can handle it regularly so that it becomes used to it. Then it will just lay limp in your hands while you stroke it. having it as a kit may also get you over your phobia. As for introducing it to your brothers jill, I have found that jills will take to kits very well and all they want to do is mother them, saying that you may want to introduce them on neutral ground.
Kits wont be around in numbers for the next few months so can get all the relevant information on health, feeding etc etc and be fully prepared for their arrival. Best of luck
