Can I borrow or can you suggest where I could get a decent Nail gun or carpet fitting equipment

Hi all

I've a bit of DIY to do  - fixing beading on hard floors, securing some loose carpet on the stairs and adding some mdf panelling to wardrobes and wondered if anyone had a nail gun and/ or some carpet fitting equipment I could borrow?  Im on the southern end of the ladder.  Some links on where I could buy would also be helpful.

Many thanks
