Lots more of my friends and family are trying to put me off having pigs!!!!!!

Can anyone please clear up a few things for me:
1. Do I have to have a special vehicle to transport my pigs to the abbatoir?
2. Do I need to wear white coat, wellies, hat when I transport my pigs either home (from vendor) or to the abb?
3. Do I need to take a test before I'm allowed to have pigs?
These are all things that people have assured me I need to do/have!
I know I need to disinfect any trailers/crates (thoroughly and with defra approved dis.) during the transportation process and there are a few forms I need to fill in (not rocket science, I do have a degree!!!(although not in rocket science!!!))
Would I be right in thinking that you may need white wellies etc if you are picking pigs up from the abbatoire and taking to the butchers?
And I am aware that you need to have some kind of refrigeration process if you are selling the meat commercially!?!?!
I also thought you were allowed to kill pigs in your own yard if the meat is for your own consumption (not that I would just clarifying a point here!)
I would be greatful of any help as people are all so negative around me at the moment!
My career has not panned out as I hoped and I really want to try something different before I loose all sense of being on this planet!!!!!
