Carpet Fitting Needed

As a result of my parents having their lounge decorated and a new carpet fitted,
we now have the opportunity to use parts of the remaining wool carpet and underlay, that are still in good condition, to re-carpet the landings and upper staircase in the shop flat.

Is there anyone out there who has, or knows of someone who has done carpet fitting and would either help me fit the carpet, or lend me the appropriate tools?
Please do drop into the shop if you have any info, or advise.

Many thanks

Sarah
