Do it yourself

I am about to cut through some carpet and put selfstick tile there instead. I have a small hallway (9x5 plus closet) where the carpet is stained and I am going to make this an entrance hallway of tile instead. I am doing this myself this evening, so wish me luck. Right now I have tacked down the remaining carpet with some nails to hold the tension. Next I am going to cut through the carpet - and, yes, I am hesitating!!!!! lol Next I rip up the old carpet - AND HAVE A STROKE AT WHAT I HAVE DONE!!!!!!!! Then I battle with the tacking strips to get those up. Then I put down the tile. I even bought a small hack saw to cut the aluminum carpet trim that goes on at the end. How long do you think this job will take me?
