I already have 3 9mm at my place so I'll use them to make it to my friends gun store where I will get as much weapons and ammo as I can get holding it in backpacks. This will then be taken back to my house where the other members of my family and my friends are currently putting metal shutters which work electronically on my windows. I dont't live in a city so have around 4 days to prepare before I need to kill some zombies. After making sure my electronic shutters work I will take apart my staircase which is made of wood and comes out without damaging the structure of my house.Then I will put a rope ladder in and make a hatch. This is so that if any zombies did get in I would have an escape route. I would also position some gas cylinders a bit away from my house which I can shoot using my sniper rifle which I aquired at my friends gun store. The gas cylinders would be replaced every time they exploded as this takes out any large numbers of zombies without wasting all my ammo. After this my whole family and my friends would all go to the grocerie store and get all we could. Two members of my family are truckers so these would be used to get all the food. I would also buy a generator for to get power. Both of the trucks would then be reinforced and totally customised to suit the new zombie environment. Locks and steel doors would be placed in all my rooms to cut off the zombies from reaching other parts of my house. As my brother and his wife are both doctors I would be sorted on the medical side of things as they would have all the stuff for that.My friend and I would then make another trip to his gun store geting every last gun and piece of ammo. With one day until the zombies reach us or so I would make a journey to my local hardware store and get all the tools and materials I may need for future developments to my house. My uncle who is a brick layer would put 20ft high walls surrounding my house with all the children doing the labouring for him and also get iron gates for the trucks to go through and i would install cameras around my house and property and have someone watching at all times. On my roof there would be several points and little bays which I could use my sniper rifle and other weapons also having heavy artillery on each side like mounted guns. Once I a week I would get all the supplys I could fit into two trucks all supplys would be stored under my floorboards which when under arelots of room this again providing somewhere to run if things got nasty.
