No need to be in a hurry Clough as I won't be doing the skirting boards for a couple of weeks at least.
As for the carpet laying, I had a quick look at the link you provided and think it's probably outside my scope of abilities. I wouldn't have the patience or skill to cut the carpet to fit exact, I'm sure. Besides, I don't have any of the tools:
Row running knife
Knee kicker
Seaming iron
Hot melt seaming tape
Power stretcher
Tackless strip
Carpet padding
Gripper edge
Masonry nails
If I decide to lay a carpet, I'd definitely call in a professional. Thank you though for the thought as you're probably not wanting me to miss out on the opportunity of laying new carpet in the hallway.
